    I bought an LS7 crate motor from a friend several years ago who purchased it from Chuck Hutton Chevrolet in Memphis in 1980. It was a long block still in the crate, painted black, with a sticker on the valve cover indicating that it needed high octane fuel. It came with a 163 intake as well. The heads were iron 990s if I'm not mistaken. LS7 engines did have the ZL-1 camshaft and 12.25 to 1 pistons along with 7/16 dimple rods.
    Put it in a 73 Camaro that I had at the time. I never raced it at the track but it was the strongest, hardest pulling and quickest revving engine I've ever owned.
    Easily the most radical sounding as well. Just an absolutely animal.
    If I remember correctly, the receipt from the dealership indicated it as "465 hp 454 special performance engine."
    I think I paid $1,500 for it. Can't remember what my friend paid for it but it did have the original sales ticket with it. I may still have it buried in some ancient papers somewhere.

    If what you are saying is correct, I would guess your “all aluminum’’ Motor would be a ZL-1 427. If my memory is right, I think there were 6 or 7 1969 Corvette ZL-1’s built.

    1970 Corvette NEVER EVER came with an LS7. GM#3965774 long block all had cast iron heads end of story. Our family bought 2 and had dealings with others who owned them. Engine code was "XCH".

    This is correct, but I do know there were some dealer installed LS7's put in at dealers where I live back in the early 70's but it's not stock.

    Post #29 on this thread pretty well covers it all.
