I am talking about everything from the basic GM 350 4 bolt main crate engine to the current LS7. I want to know what works for L98's, LT1's, LT4's, LT5's, LS1's, LS6's, LS2's, LS7's, etc.... If you can give common aftermarket heads, cams, lids, filters, throttlebodies, etc.. I get asked these questions all the time. I am sure we have a wealth of knowledge out there. We just need to share..
