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
does the ET of the car equal the HP numbers on wallce or morosso slide?
Using the Wallace calculator the numbers are off. Wallace indicates that it's making more power for the ET than what it did on Dwayne's dyno. Using Wallace as a reference point this combo would fall into the "overachiever" category.

This is a tough one, but going by my deal with the same head work roughly, I will guess 725 hp to 700 at 6600 rpm depending on dyno with a peak torque around 4800 rpm. Your dyno numbers have always produced excellent ETs for the numbers, so that is why I qualified it at possible 700 hp. I also figure this package will carry ninety five percent of peak hp from 5200 to over 6900 rpm. All in all, a package i would like to have in my other 65 dart!
Glad to see you on the board, Dwayne!

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.....
OK, Dwayne, Fess up, what did it make?

okay....here we go.....
when i was putting this motor together i told the customer it "should make somewhere around 700hp with my dyno headers.....and it will probably lose 40-50hp with the car headers".
first sheet.....2-2 1/8 X 4 dyno headers

Dwayne, you called that one pretty close.
542 CID, EZ-1 Heads
717.7 hp at 6000 rpm, 677.1 ft-lb at 4500 rpm, 2-2 1/8 X 4 dyno headers (stepped)
678.0 hp at 5900 rpm, 673.3 ft-lb at 4500 rpm, Hooker 1 7/8" fenderwell headers(long)
39.7 hp difference. Time for some new car headers
I bet even the Hooker A-body 2" fenderwells (~43" long) would be 30 hp short of the 2 to 2-1/8 stepped headers.
One more thing, with all that torque at 4500 rpm, it might push the 8" converter stall and shift recovery rpm higher than he expects.

39 Hp up top but look at the torque advantage of the small tubes at 3900 rpm  that's 67 Hp in favor of the small tubes! A heavy combo with the right gear and vert probably could et as well or better even if the top end mph wound up lower. All out race car big headers no doubt....but If this motor was in a heavy dual Purpose car I'd opt for the roll on grunt....That's really not enough head and rpm up top to warrant that big a header unless it was a real light car. Peak torque isn't that much better like a bigger head flow would bring. Maybe an off the shelf 2" x 3 1/2 would be the best balance for this one. And with a full exhaust the peak to peak would likely be less of a spread. Still an impressive motor!! Like I said I knew the Torque would be massive.

i was only off by 8 HP but missed the torque on a quick guess it would be higher with the smallish cam, heads and headers. i do find it interesting though reading some of the other guesses puttinbg a combo like that in the 750-820 hp range. just makes me wonder what the guesses were based on.  thanks for sharing,

What do you guys think it ran based on the 3450 raceweight and dyno results posted with the 17/8 long tube headers ?  In other words ; how fast would you expect a 680hp combo to go at 3450 lbs Ron

What does he shift at,Dwayne and cross the stripe at?
