Camshaft question

crackedback said

I forget which cam MP produced in both 108 and 114 variations 484 or 508. All I know is the 114 wasn't even good to use as a doorstop. JUNK

Don't know what they did for ignition timing on those test, but, I'd bet all three of them would like a different initial timing setting. No mention of that in the article, IIRC.

Focusing on the 284/.484 that was on a 108 LSA it has 68° of overlap whereas the 114 LSA version has 56° of overlap.
Big difference right there.
All I ever read from MP was that they changed the LSA to make it more street friendly, have better drive ability IIRC. Obviously they were selling the 108° LSA versions to more guys with low compression, turd converters and highway gearing......mismatched and poorly tuned combos than they were to those that were competent in putting together a cohesive combination.
