Is this guy a preacher or some other significantly religious guy?  If so, I think I remember him from the 460 forum.

Looks like a good deal, did you see the head casting number though?  I didn't think you could bolt GT exhaust manifolds to a CJ head.

You can, but several bolts will be missing. That is the case here. CJ casting numbers have a perpendicular arrangement that places "C8OE" on one side and "6090-C" on the other. C8-H heads have 3 arrangements that I've seen, none of which are angled just like the CJ's. I have several N and H heads, and CJ and GT exhausts in hand to compare. These heads are CJ's. He sold some 5k converter to someone else on Craigslist, who also looked at this engine and told him he had rare heads on it. Not a glowing endorsement, but still.

There was another Bronco guy that sometimes had some biblical quote in his sig, IIRC. This guy's name is Pat and he is a pilot. Nothing he said, nor any item adorning his shop, would peg him as a Thumper. He lives on a cul-de-sac and blew the roofs off his neighbors' houses firing up the Bronco on a Sunday. Not too preacherly, but amusing to sick people like myself.

As for your 390 build, I agree that it's the only way to go for a true budget FE build.  428 cranks aren't as expensive as most people think, but you're not likely to find a recently rebuilt 410 waiting for you to hotrod it.  Compared to the motorhome 440 Roadkill used, the obvious difference is 50 cubic inches.  That's what made the 8:1 motor driveable in my opinion.  Sooooo, you won't be able to do that with a 390.   You'll need the compression.  Doesn't matter if you have to mill the heads, use a steel shim gasket, or whatever. 

I'd love to see a hard-edged real-life budget 390 build,  starting with a basically stock short block.   I think that's a fabulous idea! Maybe make it a fair amount more "intense" than the Cropduster's 440?  Compression in the 10.5:1 range.  A cam in the 230-235 degree range?  A Holley Street Dominator or Edelbrock Streetmaster intake with some home porting, Or a used Edelbrock RPM intake.  Heads?  That's always the heart of the motor.  How about some heavily ported factory iron heads with CJ size valves?  Maybe some early ones with smaller chambers?  Or you could get "lucky" (living next to a Dulcich) and find some ported Eboks for sale relatively cheap.  Add a Holley 750 and 1-3/4" headers.   4.11-4.33 gears and 3000-3500 rpm stall.  All in a '66-'69 four door Falcon, desert fresh.  Yeah???

This is what always trips me up: too many choices. This sentence replaces several that I typed outlining what I have in non-428 and non-427 stuff. After rereading, it all sounded too voluminous too be true, although it is. I am a sick individual. I will stick to starting with cast piston, iron production heads, in a lightweight intermediate with converter and gears. First, I need help accumulating tools to check viability of used parts and proper assembly thereof. Yes, blueprinting beaters. The first real step is the restoration of a 428 propane irrigation stand for use as a break-in structure. More on that in another thread.

Holy cow!  I didn't realize that engine had CJ heads on my first read-through.   I did see the F427 intake.  That's fantastic.  You have good heads and a good intake.  That's half the battle already won.  If your short block checks out okay and you can get the compression at least close to 10:1, you're golden. 
 
I tell you what.  I like this line of thought, be it the Crop-Duster or a similar Ford (Sand-Chero?).  I will donate a torque convertor to the cause.  That is if you want it.  I have a 10" convertor for a C6 FE application.  It stalled at about 3800 rpm behind my old 428, which was too high for the combo.  The guy I bought it from said it stalled at 3300 rpm behind a 390.  It's a convertor of unknown manufacture.   I don't know if it's a great quality piece, but I have run it and it does work.  Let me know if you want it.

edit:  I have a Holley 3310 I don't need, as well. Needs rebuilt.  Free to the cause of increasing entropy.

You're a stand-up guy, paulie, no matter what they say  ;) However, I must direct you to my sentence "too many choices". Although I am deeply humbled in the 390 department by the ad in the other forum by Robert Jantzen, you should assume I have everything in parts already. I just go buy this stuff as it appears because I have nothing else to do besides reroof a garage, put up 400 feet of wood fencing, build two new gates, and clear out about 20,000 square feet of dried brush, in 110ยบ weather. Come to think of it, I may not actually survive this summer to put anything together.

The first effort will be pump gas with the cast pistons previously mentioned in the engine from the wrecked truck. For compression later, I have fish heads, 2292's with both full and half domes, and small bore shims. I also have a set of pro-ported doorstop heads with lightweight FPP's and other goodies. I've measured the valves in the heads at 2.15 and 1.73, and I don't think they are going to clear a 4.08/9 bore. They were built by a previous to go on a .040 A-scratch filled block, which I have also.

You were right about a Ranchero, although not the world-famous El Alacran you saw a while back in the other forum. This is a yellow '69 H-code that the previous owner stopped short of a full resto on, maybe because he discovered that painting over rust bubbles doesn't actually stop the rust. Anyway, it's a 20-footer that needs an interior. It's pretty light, but the challenge will be getting it to hook on the cheap.

So the engine in Pat's Fairlane is unhooked, and I'll be picking that up tomorrow.

Dang!  I thought I might have gained some shelf space in my garage.  All right, I'll keep my junk.   :)

As for the Ranchero, I whole-heartedly approve.  Different is good.  Way different is possibly noble.....or coarse and salacious.  I'm not sure, but I like it, either way. 

The problem with all this is now I want to put a nasty blue-collar-brawler 390 together.  Maybe a 410.  Factory block, crank, rods, and heads.  A big cam and as much compression as you can get.  I think the compression is the part that is a little bit tricky with the 390, given the relatively short stroke.   A small combustion chamber is super helpful there.  You can only take the quench distance down so far, and nobody wants domed pistons if they can help it.

JMO,

paulie

The idea here is that I want to eventually join the ADRA points brackets program. So, I need to dial in a consistent combo that can survive that and 2 or 3 test'n'tune sessions a month. When it comes time to chase ET's, I have bigger parts in the closet. I'm also thinking that I should build a pair of short blocks so I can rotate them out if needed.

Just came back from picking up a fresh 0-mile RUG-AJ with Hurst box/rods and McLeod juice TO bearing/cyl. The fun never stops.

Over the years I've received emails accusing me of living in a fantasy world, and that I don't have any cars beyond a daily driver, or any parts I claim to have. Could I be full of it? I dunno. I guess we'll see.

I thought WTF your moving to the Maritimes?
Atlantic Drag Racing Association.
Then me thunk that you live in some sand infested desert down south.
Arizona Drag Racing Association.
BB had a great thought.
Get something running, the clock's ticking. just saying

Yep, I saw BB's post. That is a good option for him. I'm in a different situation in several categories. But, that is a whole 'nuther discussion on a personal level that I will not get into on an open forum.

However, if guys here start getting impatient, I'll just backpedal into lurk mode. My clock is scheduled to start ticking on Memorial Day of next year.

That 390
« Reply #23 on: June 04, 2015, 07:43:51 PM »
Turns out that 390 actually did have CJ exhaust manifolds on it. More evident with the engine up on a hoist than looking down. I'm an idjit. Got the FE frame mounts with it. Polished front cover and other items. All bolts polished allen head. Seems to be an early two-bolt engine. Also did not see broken valve spring on pass side, may have been source of miss. More idjitness. Springs are triple, so big cam. Hopefully intact. Seller gave me free new Comp 953 springs in box, but they are 142 closed and 420 open. Roller only?

I mentioned before that I had the 390 on the front burner and a 428 on a side burner. Considering I need several tools and stuff to start putting engines together, I'm going to put the 390 on the side burner and put the 428 up front. It is a running, driving car that needs a master cylinder, exhaust work, and a few other items. If any of your remember tag lines in my posts on the other forum like manual valve body, Cheetah shifter, MSD 6AL, and 6375's, that is the car.

Nice score on the exhaust manifolds.  If you don't want them they will bring you some cash towards your projects. 

I think 420 lbs open spring pressure is too much for flat tappets unless you have a nitrided cam and EDM lifters.

I think you and I need to talk on the phone, King Paulie. PM me your number. Thanks.

Well, it looks like there is no PM'ing in this forum, or am I missing something?


OK, I figured it out. Perhaps I'm too stupid to wield a wrench.

I'd agree that 420 open is probably too much for a flat tappet, but maybe good for a hydraulic roller of some sort.  If those are modern triple springs, that is a BIG cam...

I'm probably using the wrong term. There is a wound outer spring, a flat damper-type spring behind that, and then an inner wound spring. The frigged one is not only broken 2/3 from the top, the space between the coils is collapsed. The flat one is MIA altogether. There was 2/3 of a shim sitting there, but the other third is also not to be found. Pretty weird. The retainers are very shiny. Not sure of the material. I'll be amazed if that one lobe survived.

I have to come up with a cam for the 521 8V. Might be able pick a juice roller that will take those springs. Thanks.
