DYNO SHEETS FOR 500" BUILD

[oldschool]

Sorry these are so late - it has been a busy summer.  Motor recap: 
500"
Indy SR CNC 368 @ .700"
Comp solid roller 272/276 @ .050  .700"
13.2 CR
T&D 1.7 rockers
Intakes:  Mopar 337, Indy 440-3, 440-2, 440-2D

The motor liked 40* timing, and we used 110 race gas.  The first one is with 440-2 w/2" spacer to a dominator flange.  It made the most power.  716 hp - 645 tq.  The other one is with a 440-2 no spacer with a 1000 cfm 4150.  It made the least power at 679 hp & 627 tq.

These sheets are with the 337 and the 440-2D dualplane.  The 337 made 692 hp and 640 tq.  The dual plane 677 hp and 604 tq.  check out the torque differnce between theese two,3800 and below.that dualplane is awesome down low!

This last one has the 440-3 w/ 1050 dominator and the 337 again.  The 440-3 made 710 hp and 652 tq.

I am driving the car now, I am using the 337 manifold.  My a/f ratio was a little bit fat, I am hoping to pick up a little more on the chasis dyno.  I will be doing that in the next few weeks, I will post the results.   Should be about 600 rwhp. 
This motor is in my 70 Cuda convertible and it is bad ass. (It is the purple Cuda in the back - by the way the green one has a 500" motor also, but has never been dyno'd.)

Freaking bad azz bub on all counts.  Wonder if that bad boy would run on E85 which LOVES higher compression? 

Enjoy your new KILLER high compression 500 ci Mopar Stroker engine in your beatiful Cuda(s) in good health!

Thanks for posting the dyno sheets Brian. 

I'm liking that 337 more and more. 

More horsepower and torque at peak vs the ICH dual plane. Looking forward to getting mine out in a few weeks. I should have some track results shortly.
