The whole thing that people are TRULY interested in is price. Now, If you got a big wallet, sure, go for it. Drop a vortec in there. See what you can do. But that fact of the matter is that a 350 chevy four bolt main is cheap but not cheaply built, and can be picked up anywhere; right along with performance parts. It's all in the wallet. Ya know? And personally, I like the mitsubishi 2.6 liter, Why put whats from here, in what's from there? -Colt
