I would never sleeve all 8 cyls of a cast block and plan on making any power out of it.

I can promise you this...if you are using Pcar castings the BEST way to make power is to sleeve all 8 holes. You'll gain power every single time.

It's done so much it's not funny and most people keep their mouth shut about it because it's an edge in racing where you have to run Pcar blocks.
