Newest version of 482 supposed to go on pump in the near future. Last version number 1 exhaust valve had a (too close) encounter with the piston in September. That P block has had number 1 sleeved, the block bored to 4.265 and bagged. New engine built on NOS ‘71 block. Using the Scat forged crank and 6.7 H beams from P block.
Key particulars: 11-1 CR, (Mahle w 1.5,1.5,3mm), Barry’s Felony CNC heads from October’s EMC. Comp beehives manipulated to 525/200 pressures.
Lykins Custom Hydro roller, (Comp Cams). 255/263 @.050, .625 lift, 112 LSA installed on 108 ICL.
Morel short travel lifters also via Brent. Erson rocker shaft assemblies with 3/8” push rods.
Victor intake via Jay Brown that has been massaged much but is around 3/16” narrower than the ports on Barry’s heads. Quick Fuel Street Q 950 cfm carb via Brent.
MSD ready to run distributor with phased rotor. If my Crites 2” O.D. tubes fit the Dyno they will be used otherwise it will be whatever 1-7/8” mongrel pipes are available at the builder’s shop.
Canton deep pan with tray, Melling HV pump.
Terms: person closest to uncorrected peak HP without going over wins a $25 gift card. Closest to peak torque gets honorable mention. Pro builders please play!

I will get in early with the winning entry... 587hp.
Need my address to send that gift card?

I'll go in for 599.

Uncorrected right ?
Where is the dyno located, it could make a difference if it's in Denver or San Diego.

My 2" Crites Mustang/Cougar headers fit on a DTS dyno. Just FYI.

Paulie, thanks for your the tip about the tubes. I would of course prefer to use them.

Sounds like a nice setup, what is she going in. Maybe we can guess a 1/4 mile time also.
Not that it’s gonna be at the track by the time this post is done but just a little extra fun.

Stangman,
It’s going in my 67 Fairlane 500. Car has a wide ratio DK all aluminum TL and 4:11s. with too tall drag radials, (275/60/15).
Car needs a shorter bias ply slick or more gear or both. Also a slipper clutch and a different trans. Oh, and a better driver too. So if you guess an ET aim high!
Good luck with the upcoming carving.

Gonkulator says
Torq 588 at 4700 CORRECTED
Powr 644 at 6500 CORRECTED
Now, how to Uncorrect those?
Altitude is a little over 2% but there's also weather - a rare day indeed is a 60F 29.92 0% RH day.
Let alone any internal dyno correction.
I'll guess 6% down for
Torq 554 at 4700 UNCORRECTED
Powr 607 at 6500 UNCORRECTED
On the car, is this NHRA Trim ie open headers, car set-up?
67 likely flat hood, no cold air?
Driving a fan or water pump?
Car weight w driver?
Sure is some big power out there these days!

Werby, thanks much for posting.
Car has open crites hood but is not sealed to carb. Driving wp and fan,(flex). Open cutouts on X pipe,(2.5”). Car not scaled, full interior, stock bumpers. Driver is 175. I thought these cars were 3400 but perhaps you have it in data bank?
I will be using East Ludlow, Ma weather station for correction input. 77’ elevation.

Yup car is in there already from 2018 BSD (how timely its this weekend!)
From last year's thread you ran
2.01
12.70-115mph
https://www.fordfe.com/how-much-more-gear-do-i-need-t161255.html
The Gonkulator & others felt the car should run at least a second & 5mph better, maybe more.
It sounded like you're shifting the way I do (slow), plus short shifting, no traction, etc.
To compare apples-apples, I ran the Gonkulator EXACTLY the same as the 2018 BSD match, but just with this new engine, shifting 400rpm higher since the new engine peaks 400rpm higher. That's still way short shifting.
Torq 588 at 4700
Powr 644 at 6500
2.01
5.42
8.20 at 91.1
12.47 at 118.7 back door, 117.6 at BSD
That's .23 sec and 2.6mph gain from just the engine.
In optimum trim, as I Gonk'ed for the old engine last year, with 4.11 gears (within .02 of optimum)
1.63
11.37 at 120.0
With the same ideal setup, driving, and new engine, it Gonks to:
1.60
7.04 at 98.0
11.05 at 123.5
Knockin on the door... .37 sec and 3.5mph gain from the new engine, in optimum trim.
Adding a 4.57 gear due to the higher revs helps more now:
1.53
7.01 at 96.8
11.01 at 123.9 any decent air or good wind gets into the 10s.
-
Say 624 hp 577 tq on dyno day.
There's plenty of flow carb to valves for rpm's. Will definitely get more out of it with tweaking. Can I ask the cam doctor (Brent) where you think the cam will roll over? 6850 ish. I would think its done by 6900 but your the man.
-
Jim requested a 6500 rpm peak with a 7000 rpm shift point.
-
Engine has been on the pump. Will post results tomorrow, get your estimates in.

What was the correction factor?
I used 6% as a guess but knowing the correction to 60F 29.92 dry sea level air (as if) would make for more accuracy.
-
Werby,
Air temp 77/1.016
Barometric 30.38 /.985
RH 60 / 1.020
Final correction factor 1.021
Thanks much for running all the numbers.

OK then based on that and 77ft altitude, that's assuming no correction for the dyno itself, I'll use a 1.026 correction factor for
Torq 573 at 4700 CORRECTED oops this is UNCORRECTED guess
Powr 627 at 6500 CORRECTED oops this is UNCORRECTED guess
(My CORRECTED guesses remain Torq 588, Power 644)

Dyno results are in: 619 uncorrected HP Correction factor of 1.021 moves that number to 632. I hoped for over 600 hp and very close to 600 ft lbs so happy with results. I originally mathed out the correction factor incorrectly, my apologies. UnCorrected hp is 619 which makes 69Shakar the winner.
Honorable mention for peak torque, (614 uncorrected), goes to team-moose.

I want to give some props to Brent Lykins for invaluable help on this build. I gave the Cam Doctor some parameters and he nailed ‘em. He also showed much patience with my innumerable questions.
Thanks Brent!

Did your 2" Crites headers fit on the dyno?

Dyno results are in:626/621 uncorrected HP/TQ. Correction factor of 1.021 moves those numbers to 632/627. I hoped for over 600 hp and very close to 600 ft lbs so happy with results. Fast67 was closest without going over at 624. Barry was one too high at 627.
Honorable mention for peak torque goes to teammoose. Fast67 I will need some contact info please.

JB: Correction of 1.021 gives
621 x 1.021 = 634 Torq CORRECTED
626 x 1.021 = 639 Power CORRECTED
(Edit - I saw the printout showing 632.6hp corrected, but then the uncorrected, if 2.1% lower, would be 619.6hp - they have to be 2.1% apart if that is the correction).
That Torque is incredible.
Was the engine driving the water pump or was it electric?
Was it by chance a victor dominator intake?
-
Werby, I subtracted 6.4 per cent of the corrected number to arrive at 626/621. I understand the math you applied. Parties should hold their tickets.
The engine had its regular wp on it for the pulls. The intake is a 2936.
My Crites tubes would not fit so 1-7/8 O.D. tubes were on it.
Thanks,
JB

Well done!
I wish I would have roamed around a bit, I was in the area playing taxi for my wife all over the Springfield/Amherst area 2 weeks ago, would have loved to see what you were building. I never think to put feelers out when I run home and most trips tend to be unplanned
Should be a rocket!

Ross,
Are you at the FE R & R?

No, unfortunately I didn’t take any time off. Wrapping up as much as I can with the 2 461s today.
