i have an LS1 laying around that ive been meaning to put in my 91 Z and figured since the motor is all out and im gonna be taking it apart to clean and rebuild i might as well go ahead and build it up. what would be stronger for boost ls1 bored/stroked resleeved to 427 or an ls2 bored/stroked resleeved to 427?

I'd go ls2 block.

definately the 6.0 litre block...IMO

427

LS2 would be stronger than the LS1. The LS7 might be cheaper way to get 4.125, and it has replaceable sleeve's.

I'd also say the LS2 block. But like 427 said you might look into the LS7 blocks, I'm not for sure what they're going for though.
