I believe there were a limited number of aluminum head L78 Chevelles made in 70....that intake was also used on 71 LS-6 Corvette..Colvin's book shows the engine codes. Sent you a PM..

No 1971 LS-6 Chevelles produced for public consumption.
Those 1st 90 days only production 18 1970 L-89 Chevelles used the 842 Aluminum heads,not 074.

1970 L-78 Camaro-Nova-Chevelle & LS-6 Chevelle used that #4492 when equipped w/TH400 trans.,that were NOT sold brand new in the state of Calif.,Nevada,and certain areas of Montana.
What is the date code showing on your #4492 carbs air horn?

1970 L-78 Chevelles used that Hi-Rise intake also.
What is the date on the #569 intake?..Does the intake have the cylinder No. on each runner?

Where are the dates located on the intake and carb?

DeWayne,

The intake date in on the underside lowered cross-over
section. It will be something like: 3.21.69

Also, the Holley numbers will be on the front of the airhorn
( drivers side ). This is a vertical face that is in the
aircleaner region.

mr70,are you sure no 71 Chevelle LS6's? I remember a light blue white stripe car I ran across in 76 that was said to be a LS6.I remember hearing a production # in the teens.

If you saw that around the Virginia/N.Carolina area,I'm pretty sure that was a dealer transplant.Sounds like the same one Sonny & Elmer saw back then too.
Marty S. tested a 71 LS-6 Mule in his magazine in 1971,but no FACTORY assembled ones have been proven today.

The transplant scenario is likely,but you never know.

Rick,

Let me see if I remember this:

No 1970 LS-6 Corvettes - right?
No 1971 LS-6 Chevelles?

If I'm not mistaken, I've seen technical listing for LS-6
application for both cars for both years. More folk-lore?

I wouldn't exactly call it folklore,but technical materials were printed before the cars were assembled and made a reality.
I believe Chevrolet had ideas to assemble these two cars for public release,but they never fruitioned once their respective production lines started.

Folklore may be the LS7 chevelles.

There are 2 brothers that drag race in DIV-1. The Abbazia Bros from Conn. I believe they built an LS-6 1971 chevelle and NHRA accepted it for B/SA. So
