Help me build my SB Stroker

I'd suggest boring the one rusted hole to find out where it cleans up. May be smarter to do that and sleeve it, than tear all the fresh good material out of the other bores to get to a sizing that works.

Shoot for 10.5 with aluminum heads.

All flowbench results are a little different. The peak numbers might be great, but, if the mid range numbers suffer, then the heads may not be as good as thought. It's a balancing act.

Hyd cams like the 60404 lunati or Comp XE275HL will get you to the 500+hp point with a stroker.
