Not Ranked
Heads
Cam
Compression
I made 400 hp with my 351W with Edelbrock RPM Performers, flat tappet crower cam with the following grind:
INTAKE: Duration: 297º Lift: 0.538 Clearence Hot: 0
EXHAUST: Duration: 308º Lift: 0.534 Clearence Hot: 0
Duration at .050" Intake: 236 Exhaust: 242
and SRP pistons pushing 11:1 compression.
Like you, I wanted more so I sent the heads and intake to FPS in Anaheim for porting and a custom grind roller cam. Troy tells me I should see not less than 450 hp after the porting and cam install and with the right tweaking, perhaps as much as 475. Just got everything back the other day.
There are plenty of matched component packages from Holley and Edelbrock (intake, heads, cam) that are proven 400+ hp.
