Apparently, Sports Car Graphic did a road test of a pre-production LS-7 Corvette... It would be neat to locate the issue it appeared in. I seem to recall a 13.8 e.t. with two people in the car.

Only one made from the factory & It's in the March 1970 Issue of Sports car Graphic.

Any way to post the article? [img]/ubbthreads/images/graemlins/laugh.gif[/img]

Re: 1970 LS-7 Chevelle ??
 

There was a article on a LS-6 Convertible in a magazine in the late 80's, the car was Black with red interior and the article said something about the car having the "Brute Force option", what was this, or was it just the writers lack of knowledge or misinformantion?

That would be Bill Clements car which was sold at BJ about 4 years ago for $45K! [img]/ubbthreads/images/graemlins/eek.gif[/img] My restoration customer and I got cold feet at the last second. Stupid, as it is said to be a real LS6, just not a real L89.

I bought an LS-7 long block from Shepard Chevrolet (Lake Bluff, IL) in the early '80's. Was a 12.5 to 1 motor w/cast iron OC heads. ZL-1 cam was not a fan of mufflers, as I recall. Dropped the compression a couple of points, opened the exhaust a little and the motor proved strong (revved like a small block), reliable and a bit more streetable than I expected. Fun.

I seem to remember reading, possibly in the SCG article, that the LS-7 Corvette was to get the same 3X2 intake setup that was on the '69 435hp engine, or was that idea scrapped early on?

-------I remember thinking that maybe the Chevelle was Bills when I saw it at Barrett-Jackson,if we are talking about the same car.It made quite a statement as the original engine was purported to be in the trunk.You would have been the right guy to take that project on,Rick,as it looked massive to me.Who ended up getting the car back then?..........Bill S

Chris,

There were two 3x2 454 cid engines planed for 1970, coded LJ-1 and LJ-2. They were basically 454 versions of the previous year's L-71 and L-68 engines and are documented in the 1970 Corvette Assembly Instruction Manual. If I recall the notes in the 1970 AIM correctly, these options were terminated late in the 1969 calendar year. The LS-7 was distinct from these two engines and would have used a single vacuum secondary four barrel Holley carburetor.

In addition to the LS-7/LJ-1/LJ-2 options, a fourth engine, LT-2, was also planned. This would have been a 454 cid version of the ZL-1... Aluminum block, Aluminum heads, etc. It must have been killed early on as there is no mention of it in the AIM.

Regards,

Stan Falenski
