LS6 engine on ebay
Is the code CRR on this block 1970 only? Could this be a 1971 dated LS6? The ebay # is #120124977308 http://cgi.ebay.com/ebaymotors/ws/eBayIS...977308&rd=1,1

Re: LS6 engine on ebay
according to my info yes the CRR is only a 70 suffix not 71,he states the date code B 7 71,, the seller might be mistaken on something I don't get it

Re: LS6 engine on ebay
even the motor photos don't look correct , in the complete shot looks to have the high rise intake like the 163 , yet the intake shows the lowrise casting # 569,, go figure

Re: LS6 engine on ebay
I had a 72 396 with a 70 L78 code on the front pad last year. Consensus here was it was a marine engine, which I believe. This is probably the same case. The 163 intake was probably the one that came with the marine intake. The seller says the other(70-71 LS6) intake is also included.

Re: LS6 engine on ebay
Ther were plenty of assembled engines sold over the counter in the early seventies that had codes . You could buy a complete LS-6 for No Money. They sold all of the engines that way. L-79's were like 370.00 for a complete longblock back then. There a lot more engines out there than You may think, That goes for all of them.

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.
