455 Super Duty rebuild guidelines
Hey, a shop I'm friendly with is rebuilding the engine of an original '74 SD455/4sp Trans Am. Their builder is sharp but is more experienced in Ford/Chev builds. I remember a thread with good tips (don't add a lot of compression, etc). Can someone point me that thread or a good article on rebuilding SD's properly? Thanks!

A good stock rebuild is all they need. Compression doesn't really do much on these large stroke motors. Summit 2802 is a great replacement camshaft for the OEM 744.

Ken was wanting to keep more toward stock.If mine and wanted more HP I would kick it up to 9 or 9.5 CR and put a cam in more in the 230-236 range with more lift.Those heads will breathe,the factory had to back everything off to meet smog.They got caught in a VW type smog cheat and had to reduce the cam in the SDs.FWIW,Tom
