FE Technical Forum / Timing curve for BBM heads
« on: May 23, 2018, 09:40:09 AM »
Getting ready to put a new curve in my MSD distributor with the BBM heads in mind.  4100lb car, 4.10 gear, TKO 500 5spd with 3.3x first gear.  Cruises 2200, no issues finding 93 oct, 9.2:1 CR with a 224/230 cam on a 104ICA

Previously I ran 14* initial, 37* total, in by 2900 with no issues, Edelbrock heads. 

My understanding, the BBMs are likely to like 32-34*?  My CR is low so can probably use a bit of initial, but fairly heavy car and fairly low RPM range with some load pushing O/D on the highway. 

Thinking of keeping 14-16* initial, use the Black (I think off top of my head) bushing to give 18* mechanical advance, gives me flexibility to run it at 14/32* or 16/34* depending what it likes.  I'll have it come in fairly quick, by 2900 or so. 

Any thoughts?

FE Technical Forum / 450hp out of leftover parts?
« on: April 18, 2018, 02:52:11 PM »
I'm still buttoning up my current 390 with BBM heads, but sort of stepped in another shortblock that I want to use to put together a collection of misfit parts. 

I have been porting a set of C1AE heads and will be using them for this build, I want an old school combo with iron heads and solid flat tappet cam.  Part of this is driven because that's what I want, part of it is cost.  This is very much being done on the cheap, but I don't want a low rpm combo, wanted something that will make decent power around 6000rpm and can shift at 6500 if really needed. 

I lucked into a Edelbrock 7505 dual quad intake for $150, and while I was picking up the intake I picked up a freshly rebuilt 390 longblock that had been sitting in bad storage, never fired.  It's going to need a hone on one cylinder, one piston was stuck but I've freed with a lot of Kroil, but the cylinders are fresh otherwise.  It has brand new SpeedPro .030" L2291F pistons, and had a brand new XE274H cam and lifters,  new Comp timing chain, Melling pump in it with stock reconditioned rods.  C4AE heads with fresh valve job, stainless 2.03"/1.53" valves, some generic springs, and positive seals. $200 for the longblock, I couldn't resist. 

I also have a 428 crank that I picked up last year that's been turned but will need polish, so plan is to use it to make a 416" from this shortblock, and either shelving or selling parts of the longblock.  I have Autotec pistons on the way, Crower EDM lifters, as well as a 247/256 .583/600 108 solid flat from Brent. 

So Edelbrock 7505, 10.5:1 cr, 247/256 solid flat, C1 heads ported to go 280/185ish, and 1 3/4" headers, 1.5/1.5/3mm ring package and a 3.98" crank. 

450hp out of the question, 500ftlbs?  Peaks at 6000/4300 respectively?  I want a "hotrod" motor so didn't care about idle, fuel mileage, or need for cheap gas.

Power estimate from a solid flat tappet combos listed by Brent and Paulie, acknowledging the heads I'm putting together likely aren't going to be as good as theirs

Member Projects / Little 390 update
« on: February 17, 2018, 10:23:35 PM »
I found a decent deal for a set of BBMs and a hydraulic roller that a guy hadn't installed and was selling as project had taken another direction.  Heads were prepped by Brent, and the roller was spec'd from Barry so it was nice getting parts from folks we all know.   Shortblock was rebuilt around 2000-2001 then sat around, has maybe 1500mi on it after I got the car back on the road four years ago.  Good runner but could use a little more power, and I wanted to get rid of the Ford Red paint and all the leaks.  I know everyone is going stroker but figured I'd throw a few more modern parts on the combo for now and see how it does.   Figured I'd get PostImage working and document the work. 



I wasn't kidding when I said it was scuzzy, I'd started just keeping the hood closed. 


Checking TDC.  This Fowler mag base is pretty flimsy so I ordered a Noga that works better, but this was OK for this purpose.  I'm just a hobbyist so didn't spring for high end machinist stuff


Picked up the big 18" Moroso wheel and practiced degreeing the existing cam since it was "known".  Turns out it was 8* advanced




Did my best not to chowder the cam screws but I'm going to need new ones, they were pretty torn up before I started

FE Technical Forum / C1AE head porting
« on: January 08, 2018, 02:24:30 PM »
I posted this topic on the Network54 site as well, but it's tough to find and recall the topic using that format.  I appreciate several folks chiming in and didn't want to lose the info.   I found several topics on porting the early low riser heads but they had Photobucket attachments which are now broken links, so figured I'd post this. 

I'm by no means an expert, or even a novice so this isn't a "how to" guide.  Just figured I'd take a stab at porting a set, get some advice from knowledgeable folks along the way, and see how it goes.  I gathered some flow numbers from various sources and old posts, I'd feel very lucky to pull 280cfm @ .600" or so with these.  I have a set of BBMs flowed locally that I can compare, as well as some Edelbrocks that are currently on a car and will be put on the bench, so I'll have numbers for reference. 

Anyway, copied from other site:

1) Will 2.15 intake valve flow appreciably better than a 2.09?  Undecided between a 4.08 or 4.16 bore at this point, most likely 4.08 though. I'd like to try a solid flat tappet, old school combo with these, so lift would not be over .600" 

2) The "knobs" at the top of the intake ports on the right half of the head, can they be taken out? Seems odd as the two left ports do not have them, not sure what purpose they serve but they're obviously right on the roof where velocity is high and if possible I'd like to take them out.  If they need to be retained, can they be shaved down a bit, and radiused into the corners of the roof? 

3) The intake ports have a 45* or so chamfer on the roof at the entry.  I'm planning to basically raise the roof enough to flatten that chamfer to the roof and blend it back into the port, any issue there?  It's abrupt enough, seems that it'd cause turbulence at the intake junction.

4) The vertical short turn of each port, can I lay that back a bit?  The inside wall of each intake port seems a bit "hooked" and seems it would bounce flow out towards the outside wall.  Looks fairly simple to straighten that out and blend it into the runner as I'm doing a light gasket match?

FE Technical Forum / Chassis dyno results, tuning advice
« on: December 22, 2016, 12:16:27 PM »
Ran the car today on a DynoJet just to get a baseline.  Basically, I'm not really happy with the way the car pulls but I've been playing with the tune and can't really seem to get it much better.  Last night I pulled 2* of timing out of it to be safe and hit the dyno this morning. 

390ci
Holley 750dp
Performer RPM
Edelbrock heads with light bowl cleanup
Comp 270H 224*/.519" on a 110LSA, installed at 106
9.5:1
FPA 1 3/4" TriYs



So, it peaked at 302hp at 5400, 369ftlbs at 3500.  As a reference, made 280hp with 3* less timing in it, and sounded and drove a ton lazier so big difference.

Numbers back up how it feels in the car, it's a torquer around town, kind of surprised it made peak power at 5400 as it feels flat after 5000rpm. 

Flywheel numbers, which I'll estimate since I think guys are more familiar, would be 380hp/460ft lbs using 20% loss. I figure my setup, optimally, would make 400hp on an engine dyno, throw exhaust on it I guess this isn't too bad.  Not sure I'd believe 460ftlbs as I don't think any similar builds come close to that number. 

If you read the AFR chart though (the dotted red line is 12.5:1), car is tuned fairly well on the hit, but then goes dead fat until 4200rpm or so.  That's about how it feels if you roll into it in say 3rd gear and it has some gear to work against....very soggy.  The peak A/F ratio at peak is perfect so not sure I'd mess with the jets, just not sure how to lean it out before that point?  I don't think a lower power valve would make much difference as this is WOT and I'd think vacuum drops immediately.  Any ideas?

Non-FE Discussion Forum / Kind of interesting, 429SCJ stocker dyno'd

Don't see too much about these motors, being just a two year option.  Was always curious how they'd run with the solid cam as it seems to match the big ports better, pretty impressive 6000rpm peak.

Everyone knows the 375hp rating was bogus, but the Holley and solid cam seemed to really wake these up.  My understanding is stock cam is 226/238 .509/.509 on a 114.  Don't have the time to lookup how that compares to 427 cams?

Member Projects / TKO 500 into '63 Marauder
« on: June 01, 2016, 12:47:33 PM »
Figured I'd do a brief write up of the Tremec TKO 500 swap into my '63 Marauder, as there seems to be a LOT of differing experiences/opinions on putting these trans into the early fullsize chassis.  Specifically, how to build the trans crossmember, floor mods, and clutch linkage modifications. 

Just a little background, I converted car to a T10 because I got it cheap with the pedal/clutch linkage setup.  Rebuilt the T10 and used that to get the car running and debugged, using an old Centerforce clutch I had laying around from my former '76 F250.  It performed fine and was sweet shifting, but that 2.3x first just killed the feel of the car.  I eventually threw a cheap 4.10 open rear in the car which finally made it work OK around town, but I drive the car a fair bit and it just killed the highway manners, 60mph cruise was around 2600rpm and with my exhaust setup just felt like a "hectic" ride. 

Here is the car


Engine is basic .030" 390, 750dp, Performer RPM manifold, bowl blended Edelbrocks, 270H Comp, FPA Tri Ys, ~9.5:1 cr.  Nice torquey combo, but still needed more SLR, but plenty of torque to pull 2000rpm cruise in OD so we'll see where I end up with rear gear, thinking the 4.10s will be perfect.  Rear tire is a 275/60/15. 

I bought a Quicktime bell, TKO 500, aluminum driveshaft, offset shifter from the classifieds on the Network54 site.  I would've gone for a 600 if buying new as the cost is the same, but this should work just fine for a street car, and initially I wanted to re-use the Centerforce clutch.  I also switched to an FRPP steel flywheel, didn't see the sense in putting an old cast iron flywheel in a $600 bellhousing. 

First thing noticed is that with the internal shift rails up top, the TKO is much more squared off and taller above the centerline than the T10, especially in the tailshaft area. 


The overall length is different between the transmissions.  However, with the different depth of bellhousings out there, there's no "definite" answer on whether the old driveshaft will work, as the package of trans length and bell depth will effect the total length. Therefore, best to just measure what you have and adjust accordingly.  I got an aluminum driveshaft in the bundle so I didn't have to modify my existing, but as I recall it wouldn've just needed 1-1.5" cust.

The mounting pad is further back on the TKO, and the bolt holes are at a slightly different center.  Also, the body of the gear case hangs "lower" on the TKO, meaning you'll have to notch your crossmember.  Not a big deal, but I'd say this is a definite on any swap.


Because the mounting pad is further back on the trans, there's a need to move the crossmember to the rear in the chassis.  I believe it was 2-3" but I did this last year, then moved houses, so don't have my notes.  Either way, not a huge issue.  There are several ways to move the mount, you can go bigtime and cut the mounts off the frame and relocate.  This would require widening the crossmember as the frame gets wider in that area as you move back, that seemed like a lot of work for no real benefits that I can see.  You can section the crossmember and move the mount back in the middle, or you can weld "tabs" on the crossmember mounts and move them back.  I chose the latter, less work and I was up against a time constraint last year to get the car mobile as I was moving.  If I did it again, I'd choose the second option and section the middle of the crossmember as I believe it's a "cleaner" install.  You'd likely have to mess with the Ebrake mount either way.  Pics show the small notch I had to take out of the crossmember flange to clear the main body of the trans, and the "tabs" I welded on to the crossmember to locate it back on the frame.




Also, if you have an early clutch fork (I reused the stock fork i had which has the wire clip), the pivot point is different than later bells/forks, so the pivot must be moved.  I measured it at ~3/8" outboard and redrilled. Again, tight timeline dictated using what I had, I'd definitely just buy a new fork with the spring clip retainer if doing this again.



Another minor tweak, as stated the trans mount dimension is different on the TKO, so had to drill/slot the trans mount to match.

I'm working on installing a TKO 500 into my '63 Marauder and wanted to see if you guys had some suggestions.  In short, I did this install last year, very quickly, in order to make the car mobile as I was moving and wanted the car under power.  So, it was "done", but I wasn't happy with the install.  I also had an issue with the used trans, so decided to pull it back out and do it right. 

Couple items I didn't like:
1) Stock clutch fork uses the wire clip and a different pivot point than the Quicktime bell I had.  I redrilled it and used the old style pivot, but not optimal.
2) The TKO bolted up fine with some extensions I put on the trans crossmember, but the mounting bad to output centerline distance is different on the TKO, so basically the output is 1.5-1.75" below the old T10.  This tilted the motor down, and messed with the mechanical clutch linkage and throttle, besides just not being "right". 
3) This was a "frankenstein" setup, bought used, so I didn't have all the pieces together.  I basically could not adjust the clutch such that it would fully disengage without hitting the floor.  The quicktime bell has zero access to check air gap, but could tell it was still dragging.  It would shift, but not well.  I have an adjustable clutch pushrod, but still not enough throw.  I think I need a clutch fork with more "curve" to it to give more throw with the same amount of travel.

So, really my question now is what are people using for clutch forks with a Galaxie/Marauder chassis, and quicktime bellhousing?  I understand McLeod has discontinued their clutch forks, so that plan went out the window although I'm guessing if I look around enough I can find one on the shelf somewhere. 

Any help is appreciated.

Private Classifieds / T10 setup for Galaxie
« on: July 08, 2015, 12:45:51 PM »
I have a narrow pattern bell, fresh T10, new Hurst shifter and rods, flywheel, and aluminum driveshaft to put a T10 in a 60-64 Galaxie.  Trans was behind a mild 390, street tire open diff car, not abused. 

I just pulled this out of my '63 Marauder, approximately 500miles on the setup, less on the driveshaft.  I found a great deal on a TKO500 so went that way. 

T10 rebuilt by me, all new bearings, sliders, synchros and 2-4th gears purchased from Ed Hartnett.  First is a little noisey but otherwise it shifts great, absolutely doesn't pop out of gear. 

Hurst shifter was new at time of install, bought it from Dan Williams, along with the rod kit, setup cost $500.

Bell has partial chipped ear but otherwise perfect, doesn't effect install. 

Driveshaft is a 3.5" aluminum Shaftmaster with 1330 joint and new Spicer yoke and ujoints. 

$600 obo, I'm in Virginia but travel to Pa frequently and would deliver to mid atlantic for the right situation. 

PM with any questions, thanks.

Considering doing one of the simple self tuning EFI deals for the Marauder, and got to thinking about intakes.  I feel the motor is well matched now, Performer RPM on mildly ported Edelbrock heads, 270H, 9.5:1, 1 3/4" headers.  Basic motor.  But just hypothetically, if I went with a typical 445" with 10.5:1 and healthy hydraulic roller, some more head porting.  I think this is the point where the Victor could make more power.  Being in a heavy car though, i'd lean to a dual plane.....but there the question lies, does the EFI make up for a lot of the lowend loss of a single plane since it doesn't rely on signal to the carb?
