This is for the 455 in my 85 Cutlass, wrong forum I know but just pretend I said 85 grand prix
 . I have a 70 olds 455 with the C casting heads and I have to pull this engine to swap it into a solid body. While its out im going to regasket it and am thinking of dropping a different cam in as well as this engine has never really had any pop for some reason. I think i had a factory cam put in by the place that built it the first time. I would just like to know whats a good cam choice for a strong street motor? On 442.com faq section they suggest a mondello JM20-22 i think it was. I am also running a holley 900cfm pro jection on this motor. It is way to slow for a fuel injected 455. Any help from anybody knowledgeable in olds engines would be appreciated.Thanks again!  GR-RRR!
