Re: 1971 LS6 Chevelle SS Production
Yeah, I have one of those 1972-dated "CRR" LS-6 engines also that has no VIN up front. I've had mine for several years and have actually ran across several in my travels. I'll check mine for this number up front. Another member, Tirebird, also has one of these 1972 CRR LS-6 engines. They are kinda rare in the fact that they are 4-bolt "289" blocks, but I believe they are just crate engines. Why Tonawanda chose to stamp these with the 1970 TH400 code of "CRR", instead of the usual "CE", I don't know. They were complete engines including intake manifold and were just covered with 1972 casting dates on everything including the closed chamber "291" cylinder heads. Crate LS-6's were known for having Open chambered heads so this short run of accurate "1970 Close Chamber'ed LS-6's" are kind of interesting. Actually it would be kinda neat to put one into a 1972 SS454 Chevelle and leave the experts scratching their heads!
