Here's some info/ questions on the 454 going into my 72 nova. Casting 140145445 marked "hi perf" ...mean anything? Heads are 820 castings mildly ported, cut for big valves and milled to achieve 10:1 comp with forged .125 dome pistons. cam has.520 lift supposedly crower copy of 375hp 396. Wish I knew. Intake is edel perf. 3.73 12 bolt. Need to build tranny and get converter. Any suggestions on changing anything before I finish putting it together? Thanks.
