well my ZL-1 engine finally showed up...

[black69]

My engine was supposidly in a dragster, and now I have it based on research, it was in a rail. Still trying to run down who did the first build that tried to squeak every once out of it as far as horsepower potential, and thus find its true home.

I thought some would enjoy speculation, i.e. the chevy ZL-1s making the numbers in 71-74 were actually yenko zl-1s. One of the top guys was a little too close to don yenko's location to not wonder [img]<<GRAEMLIN_URL>>/smile.gif[/img] He was a little over 2 hrs away from cannonsburg.

check out the list of record holders. there are 2 pages.

Yenko was given permission by Chevy on Aug 1, 1974, to purchase ZL1 blocks from Winters Foundry.

Before that, they were bought through Chevy

My block is obviously before this 1974 arrangement, and is from the laporte foundry. To me it is possible, those drag cars making the times before 1974, were reinforced 052 blocks made by yenko (like the one I have). Thats my thought for the day.
Why the yenko stamping are hidden behind the timing cover is interesting also. Why did he do that....
From the outside it looks for the most part as a 052 standard block.
