LM7 max lift? Anyone know what LM7 valve springs can handle stock? I'd like to put in a stock LS6 camshaft before I drop the 5.3L in, but worried about valve springs, and possibly valve-piston clearance.
I don't really want to pull the heads and change springs at this moment. Plan to pull it out in the next year and either build a new motor based on a 6.0L block or fully do up the 5.3L into a 5.7L and so on. Just figure for now, if I can find a used cam cheap, why not?
