Hello, I have a 5.3 Vortec motor and these blocks are everywhere, I've heard of putting in 4.8 pistons to increase compression in the 5.3, but I found a 5.3 block with a destroyed crank and pistons, is it possible to bore out this block and buy 350 (101.6mm 4 inch) pistons???? or where can I find 96mm pistons that are not expensive? the 350 bore is the option I like more since there's many companies that make pistons for a 350 bore. But I like the challenge and fuel economy of this 5.3, I know with cam and etc it won't make as good fuel economy, but a 10.1 ratio sounds nice to me. I want to see where this engine can go and if I can find reasonable pistons, anybody know of any for it??? then it's definetly worth diving into.
So my question is: Can you bore a 5.3 to a LS1, 6.0, 350, 327 bore?
(I listed all those motors because their bore is the same 4 inches)
