Sleeved Blocks...B series HawnDUH..?

[gforce71]

i'd stick with stock sleeves unless your planning on making like 600+

most bseries blocks are only reliable on the stock sleeves up to around 300hp. I know people running more and are fine for now, and some people running less that have blown there shit up. it comes down to the tune pretty much.

TRUE I have seen an LS block crack a sleeve wide open with only ~12psi ~220whp
