actually....more like a "what did it make" post.
its a motor i did for a friend of mine last spring.
some of you already know the numbers......so you guys cant play

the plan was for a relatively low RPM BB that would run on mixed gas, and be low maintenance, and run 10.0's at 3450lbs in the summer heat.
the original plan was going to be based on a stock 440 block bored .030 over with a 4.250 crank, for 505ci.

then, the decision was made to use an aftermarket block.

once that decision was made, then it didnt really make sense to stay with 505ci.
i decided on a 4.440 bore with a 4.375 stroke.....542ci.

then, it was deemed worth the extra $$$ to lose the 150lbs by using an aluminum block rather than a heavyweight World iron piece(over 300lbs).

so, its an Indy block, 4.440 bore
*eagle 4.375 crank
*eagle 7.100 rods
*custom Diamond inverted dome pistons, 11.7cr
*plain, old, boring 1/16, 1/16, 3/16 ring pack, std tension oil rings
*EZ-1 heads, chambers ported, bowls blended, valve job, flow 340/230
*roller cam, 272/278-112, .650/.630 lift
(the heads and cam actually were used parts that came from Mark Gates 511 Pacer motor)
*HS 1.5 rockers
*older, non-HP 1050 3 circuit dominator(also from Marks 511)
*440-3 intake
*Hooker 1 7/8" fenderwell headers(long), 3.5" collectors
*center sump deep pan with single line external system

then.....its going in a 3450lb Dart with ladder bars and 30X10.5 radial drag slicks, 4.10 gears and an ATI 8" converter.

lets hear what you got to say.....

760-780hp


10.30 10.40s

Sounds like it should solidly be in the 14's, maybe a high 13 with some tuning. .....ok...ok...I cant play. Now I'm bored.

The 440-3 intake is M.W. port size so I'm assuming the heads are to, aluminum block deduct 30 HP so I'm guessing between 800 and 820 HP at or close to 7000 RPM

evrything similar to my motor except for the cubes and my challenger goes 6.20s at 110mph at over 3500lbs with full exhaust on the car in the 1/8th

so bigger bore, that engine goes 750hp and that car is mid 9s

It's 80plus during the day you call that winter? I'd like more info to make more than a WAG. If it only runs 10's you got a tune up problem.Good to see you around.

are the 1 7/8 headers small?


9.90 -10.10 is what I would say. and 745hp

Either these hp numbers are high for the et predictions or...? I doubt my junk makes 700 and its running 10.0s at 100lb heavier..
FWIW I think 9.90 to 10.10 would be a good guess, although the displacement may help get the car moving quicker so it may dip into the 80s. You have more duration but the displacement should eat that up.

My guess is around 785...Hmmm...Mark Gates..How is he doing,Dwayne? Haven't heard that name in a long time!! Does he still have his fishbowl??

Did the heads have the platinum series port work done to them ?

Guesses so far:

Ari440 760-780hp
Cab Burge 800-820 HP
sixpackgut 750hp
GwaiiEagle [Email]767hp@6500[/Email]
70blackfish 745hp
Kevins493 ? less than 700 ?
tboomer 785
S/ST 3040 760 HP
440Jim 690 hp at a low peak rpm ~6200

730 @ 6600

i'll guess 710 but I agree with Jim

I'll say 720 at 6200, the combination of the small exhaust tubes ( collector size is 3.5 so it's probably not quite as bad as it looks ) and EZ-1's built-in 'kinda meh' exhaust flow (compared to a raised port) is going to force the peak RPM to be a tad to the low side, peak torque should come in around 5000 but with the cubes and CR it should be EPIC all the way there. The wider 112 centers should help the torque hang on a while though. An exhaust limited low Peak torque RPM has a way of lowering the HP curve trajectory, but there's F.A.S.T. ways of getting the torque not to drop like a stone.

The guess is on the high side for most but I know Dwayne knows how to make the most of that EZ intake port.

I was gonna ask why not use a raised port but then I realized you probably are dealing with something that might have to fit back into a Fishbowl

I've seen the car run and it leaves real hard (3-4ft wheelstands) and 60fts very well for the weight. You'll be surprised at the power numbers VS ET's for this beast.

I know what it made so i can't play



Ron

My guess would be right around 700 hp. Ron
