Re: LS6 engine on ebay
Yep, that 'CRR' block stamping was used up until about 1972. Why they weren't stamped 'CE' like most other crate engines, I don't know. I currently have one of these 1972 CRR LS-6's in my '55 Chevy Gasser. It happens to be a '289' casting for the cylinder case but also has the closed chamber, rect. port cylinder heads and pancake aluminum intake manifold with all 1972 casting dates.
