I am the owner of a 67 Corvette and read the board religiously. However, I have a Chevelle question if you don't mind. I looked at a 71 Chevelle yesterday that had a LS6 in it. I have heard that GM produced around 14 of these from left over engines from 70. Does anyone know if this is true? Thanks

Re: 71 Chevelle LS6
I own an Org. 67 Chevelle SS 396 ragtop. All paper and Build Sheet. ( Unique looks like an IBM punch-card.) I've heard that story as well. Bottom line. The car should have EVERY bit of paperwork to justify the legitmate price a car such as this will command. If not, treat it as it is. A maybe and priced accordingly. -

Re: 71 Chevelle LS6
The Chevelle guys are still looking for that elusive 1971 LS6 -- if one turns up it will be rarer that a 1969 Corvette ZL1. As Jay says, it better have iron-clad paperwork and owner provenance from build to present day. Any left over 1970 LS6 engines likely would have gone into the service parts operation once the 1971 build began. One can dream, but I wouldn't waste my money.TerryComment

George,
If you haven't already, go the The Supercar Registry and ask over there as well (www.yenko.net ).

Re: 71 Chevelle LS6

I think that folks looking for a 1971 LS-6 Chevelle are going to be looking for a long time and will still come up "dry".
Keep in mind that the 1970 model year was the last year for "high compression" engines (at least, for a long while; almost everything comes back eventually). For 1971, compression was lowered to follow a GM corporate edict that all 1971 engines be capable of running on regular fuel (in anticipation of the introduction of regular grade only unleaded fuel). I seriously doubt that GM would have compromised that edict in order to "use up" a few 1970 engines. I think that they would rather have scrapped the engines than do that, but they didn't have to scrap any such "left over" engines. They could simply have transferred them to GMSPO for SERVICE use. I think that GMSPO would have been very capable of "absorbing" a handful of engines. After all, the engines were still available in SERVICE after the 1970 model year.In Appreciation of John HinckleyComment

Addendum
Also, keep in mind that 1970 emission control regulations were different from 1971 regulations. Very likely, it would have been completely impractical to install 1971 emission components on a 1970 engine and there may have been no available components for a Chevelle installation.In Appreciation of John HinckleyComment
