Specs on a 454 330HP
I was wondering if any one out there knows the specs on a 454 with 330 horse. I need specs for intake valves, exhaust valves, compression ratio, and camshaft intlift and exhlift. I have a computer program called DYNO 2000 which simulates a dyno test based on the information you give it. Its a pretty neat program and it would help on deciding what kind of mods to make during the winter. If anyone could point me in the right direction I would be greatful.

run a search for them they have been posted in the Tech forum several times. I even posted the print out from that program on a 330hp. Also check out the desk top dyno for Denis More it is on the first page.

Compression ratio for the 330 is 7.8:1, intake valve is 2.065 dia., exhaust valve is1.720 dia., camshaft is 289/302 [email protected] lift, 214/[email protected] lift, .461 intake valve lift, .479 exhaust valve lift, wit 1.7 ratio rocker arms. Lobe centerline is 115 degrees, with 64 degrees overlap. I'm sure someone will correct me if I have the info wrong.
