Well they all have roller camshafts, true 9:1 compression, better rings, better heads, don’t leak water out of the exhaust manifold bolt jackets, seal better on intakes, valve covers. The 5.2 camshaft is a better decent RV grind as well
k.. i only plan on using a block, just wanted to make sure there wasn't something bout that.. i have LA roller right now but only 318.. keeping a eye out for a 360 roller, there is a 1990 near me for $300 but has magnum heads so not sure if it would have the la oil holes drilled.. guy could also be wrong on the year.. not sure what year the magnum came out
