what are the EXACT difference. for instance i know one if forged, one has heads that like spray, the other has heads that crave boost. what re the differences between these two motos. pro's and con's. can someone give or find me a good write up on them?

no one?
wtf mate?

The LSX engines are aluminum and 6 bolt main. It is a totally different engine than the LT line. I think the LT still used distributers too.

Does that answer your question?

no one?

you remind me of Hog, lol


anyway, i'm not an expert on either. i can give you information on both, as much as you'd like. can't find a writeup/comparison between the two, however.

lt1 second generation 350 with reverse flow cooling that allowed for higher compression, ls1 third generation 350

besides i thought u were a mopar man, shoo away from the chevys. shoo i say!

I remember reading somewhere that the LT1's rear main seal sucked and would break under boost.

heh...I wish my caprice was a 9c1...

The LT-1 and 4's used a one piece rear main seal that is prone to leaks. I had a LT-1 in the SS before the gen I I stabbed in there. No skol like the old skol. The opti-spark is a pain in the ass and it needed to be upgraded. The coil on plug like the LS engine is much better. The LT was backwards cooling. The LS changed the firing order to make a better torque curve, which it does.

wow, i need to read up on anything in this thread, i don't know pretty much anything about my ls1 engine. so yea, what the heck is an opti spark?! lol
