We run 40 lbs of boost in the outlaw car I run, and the SBC is fine, but the LSX is better. The 6 bolt heads only happen on some LSX blocks not all of them. Some of the inherent advantages of the LSX are in the block. Deck height, cam height over the crank, 6 bolt mains, avalibity of aluminum blocks, etc. I give the small block chevy 10 years or less and I bet chevy does not even make the crate engine any more.

I'm probably going to piss some people off but it is kind of like putting a carb on an LS engine, Why would you unless your scared of the technology.

Just my redneck .02 cents

im not sure what your comparing here. the LSX block, (gm performance block) are all 6 bolt heads. and thats the benifit everyone saw in them. no more pushing water. the downfall of the LSX block is its weight. then again your comparing it to the LS1/LS2/LS7 and 6.0 iron blocks. none of them are 6 bolt heads and all have water pushing issues at high boost. they all have thier advantages and disadvantages. you can add 6 bolt head options to the stock blocks but then your getting high costs. i agree the LSX block is cheap for what it is (1899) but if this block is good to, why not? if you can use LS1 heads on it, you can use LS1 intakes, so cheap FI also. its a big give and take issue. could fill a niche thats needed IMO. now all we need is cost.
