Here it is:

Holley 950hp
Edelbrock Rpm air gap which is also portmatched to the heads.
jesel valve train/Isky red zonelifters
Brodix Race Right CNC oval heads
Cam is lunati 502a4 adv dur:287/295 dur @50:256/264 lift:660/660 lobe sep:110 rpm range;3,000-7,000rpm

SRP pistons with heads comp ratio is 10:5:1
Manley 6.135 Rods
Scat crank forged, nitride ect 3.76
Block Gm 454 bored 30 over

As you can tell by now this combo will make a 427 Im just not sure what to look for as far as numbers. So if anyone can helpme out thx...

Anthony,

About 570 BHP at 6500, no idea on torque, but,
enough!

Nice motor, Harold knows a lot more than I but I think it will make a little more power, closer to 600.

I also think it may prefer a single plane intake, like a Victor Jr. The Air Gap is a great manifold but with heads that flow that well and that much cam I think a Victor Jr. "may" produce more average power, more peak for sure.

Does anybody know of any other way that I could squeeze some more HP out of this combo? Is the use of nitrous a possibility even though I really didnt intend on using it when I first put the combo together. Thx for any comments.

UD Harold how much more power could i expect from upgrading from the lunati 502a4 to a lunati 502a5.

Thanks

Hi Anthony,

On the 427 I would definitely recommend the Vic Jr too. That thing is going to love to RPM.
Have you got it running yet?
On the cam, I like the A5 but would prefer keeping it at 110 for a mostly street car.
It will probably make slightly less peak torque than on the 107 but I bet it would not hurt the HP number a bit & the heads will like the lift.
Another option if Harold feels the cam you have will be stable is 1.8 rockers,, especially on the intake.

Thanks again for letting us help with your project :beers:
