Critique my mismatched Teen Build.

I ran a 300 duration 507 lift solid from Isky in my 340 before it went boom. (Split the block at the decks) I had to re adjust the valves after break in and that was it. 5 years it ran without a single adjustment.
Good quality valve train parts seems to be the key. Manton pushrods, Crower springs, locks and retainers, SS I stainless valves and Mopar Perf. solid lifters. Speed pro roller rockers. About the best valve train my engine had seen. 7800 rpm on a couple of occasions and I think it may have wanted to go higher as it bounced off the msd limiter a few times pulling the whole way up.

Moral of the story here is solids will work great on the street if you spend a little extra and get good valve train parts. Mine was a little noisier than the 484 mp hydaulic I had in it previously but not bad.
