Re: 555 What do you think?
My 555 is very similar and I had it on the dyno! Recommend it to anyone, but here are the specs:
Dart Block 4.560 bore
10.3:1 compression SRP pistons
AFR 325 CNC heads using the springs that came on them
Dart 4150 Intake
4150 Pro Systems 1050 carb
Timing locked at 34* (verified on dyno to provide the most HP)
Straub Solid Roller 253/263 @ .050, 722/705 Lift, 107 LS
After 12 dyno pulls we got 764 HP @ 5900 rpm and had over 700 torque from 4400 to 5600 with peak at 738 @ 4900. Made 14 more HP with a 1" spacer but no room under the hood for it. (71 Camaro with 4" cowl) I had told Chris I wanted 750 HP and to keep the RPM's down, he provided that and them some! Now to get it to hook!!
