`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 https://www.yenko.net/ubbthreads/imag...ns/shocked.gif plus 2 taxes 15% here in Canada from my GM parts dealer. https://www.yenko.net/ubbthreads/imag...lins/frown.gif

I was looking on the web at a site that has the new block listed and it is $6,250.00. They seem to have a pretty reasonable price on most of their engines although I only started looking recently.The link is-

Check with your local dealer. I bought mine for 5050.00 but that was several years ago.

Re: how many zl1 motors were made
 

Another https://www.yenko.net/ubbthreads/imag...ins/stupid.gif question if you please.

Can this new ZL-1 block support the use of the later
14011077 heads? Obviously, these heads don't require those
special two inverted lifter valley head bolts.

And while I'm on that subject, can annyone tell me where
you can get the correct head bolts for this monster? I
remember seeing a complete set of NOS ZL-1 head bolts on
eBay two years ago. EXPENSIVE! https://www.yenko.net/ubbthreads/imag...ns/naughty.gif

Re: how many zl1 motors were made
 

You will have to go with ARP bolts. They don't have a set for this application, and they don't have studs to fit. You have to measure each bolt-3 different sizes for 074 heads. The new block has deeper threads so the NOS bolts are not the best fit.

Re: how many zl1 motors were made
 

On the original question, can't tell but remember a GM executive and former NCRS president gave me an estimate of 300 +. Probably conservative

Have a block, ex Greenwood. Which has GM stamping on the pad of 1-8880-A, Porterfield gave me copies of some GM notes that indicated similar numbers went to McLaren and think Donahue (have not looked at them in 10 yrs.)This was dated in the 70's and may have been Can Am blocks, but the numbers were in the same range.

People talk about these being sold by GM, personally think most were back doored.
Who would pay the price of a new car, to buy an engine that in Drags was no advantage due to the weight cap, and in A-prod they were not referred to as grenades for nothing.

Remember in a early Vette mag a photo of Greenwood clearing out the last 16 around 76 or 77.

Wish GM had kept better paperwork.

If they had better paperwork it would take away the mystic. https://www.yenko.net/ubbthreads/imag...lins/smile.gif

Re: how many zl1 motors were made
 

Here is something that I found in another forum. I guess it refers to "production" GM motors only. Don't take this as Gospel of course, but FWIW:

"A total of only ninety (90) ZL1 engines were built: fifty-four (54) in the COPO 9560 manual transmission configuration, thirty-four (34) in the COPO 9560 automatic transmission configuration, one (1) in the COPO 9567 manual transmission configuration, and one (1) in the COPO 9567 automatic transmission configuration for the other prototype Camaro.

"Of those ninety engines, sixty-nine (69) were put in COPO 9560 cars (47 manual, 22 automatic), two (2) were put in 1969 Corvettes, and two (2) were put in the COPO 9567 cars, leaving seventeen (17) crate engines (5 manual, 12 automatic)."

Re: how many zl1 motors were made
 

Those are Camaro engine totals. A whole other batch of Vette engines were made (that have the Vette engine codes on them) and lots of bare blocks.
