Approx. HP for Big Block?
Any idea on the approximate hp my big block motor will crank out? Its a 454, .030over with crane hydaulic cam 292-2 , Merlin heads, 310cc intake runners, 119 cc combustion chambers, Crane Gold race roller rockers with GM high rise intake and Holley 780 dual feed carb

You could probably use more carb to get max HP w/ your combo. Your exhaust system can also have a big affect on the numbers. Car Craft just ran a bigblock comparison between Chevy, Ford, Mopar, Buick, & Pontiac. With a similar combo the Chevy 454, using an 850 Holley carb if I remember right, put out something like 530 HP- I'd guess that you're somewhere in that neighborhood.
