Re: how many zl1 motors were made
Can someone please point out the EXTERNAL differences, between the new block and the old block? I want to do a ZL1 clone for FS/FAST racing, and I've about given up on finding an original block to work with.

Re: how many zl1 motors were made
The new block has thicker deck and main bearing area. Good for 900 HP.
 What I have been told is anything over 800HP on the org blocks BOOM They won't hold up.

Kim
That's a good question. I can't remember where I put the paper work. I'll have to find it and let you know. Is there some significance to the number? Rick

Re: how many zl1 motors were made
Dah Steve I didn't read your question right. The block outside looks very close to org. blocks. There is no winters flake on the new one also the grain look of the block is different. Hopes this helps.

Re: how many zl1 motors were made

I know a guy that has 7 of the original ZL-1's. One is out of his 4000 mile orange ZL-1 Vette and the other 6 were over the counter [/ QUOTE ] Every discussion on ZL-1 Vette's that I have ever heard about only mentioned two. One yellow and the other white. Where did this orange one come from? Is it verified as a true ZL-1? Steve

Re: how many zl1 motors were made
`after owning a couple of the vintage ZL1 blocks / ZL1 motors I think now I would rather own a new block like this one here in the box, wow what a masterpiece. Too bad it's almost twice the money $10.k minimum cdn
 plus 2 taxes 15% here in Canada from my GM parts dealer.

In other words, can you mount the original ZL-1 top end, distributor, oil pan, timing cover, water pump, original crank, etc..? Steve

Re: how many zl1 motors were made
yes you can and I will if I can get one reasonably priced, I have another pair of NOS 077 ZL1 heads and an 198 intake I was saving to use on my next project, but this one i was going to make it 12-1 comp ratio.
