Sure i can build a 496 chevy that makes great power but the pontiac just flat kills it on the street!

I love many engine brands but times have changed!
BBC 467
10.1 compression
AFR 265 heads (340 CFM)
Edel RPM intake.
228/238 @ .050 hyd roller, .549 lift
111 LSA
573 fl.lbs at 3800 RPM
TQ through mid is 585 - 590
591 HP at 5300 RPM
HP ramps up to 628 HP at 6200 RPM
Looked at a few "mild" 496 dyno sheets - TQ numbers are 640 plus
In most cases traction is the primary issue on the street.
