What would the stock compression be for a 73 454 with 346236 heads, need to know before I order a cam. Stock pistons, 30 over.
I'm not 100% sure but I think a 73 454 would have flat tops as stock pistons.What are you replacing the cracked pistons with,that would determine your new compression ratio then pick the cam you want..Date code 73, H581P domed cast pistons, 2 are cracked due to detonation. Built by PO
Is both head and block code 73? Or just the block?Date code 73, H581P domed cast pistons, 2 are cracked due to detonation. Built by PO
Ok never heard or seen so early 236 heads?Appreciated the feed back. I was planning on using the same profile piston, either cast or forge. The block and heads are matching 73, close date as well. Air Gap intake, 750 Holley VA, HEI, headers, m-20, 3:42 posi, all that is the same as was used. Before I change cams I would like to know the specs, Crane HIT 292-2 NC, know one seems to know, it is in good useable condition.
