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

[black69]

The engine I purchased sight unseen/rolled the dice, finally got here. It definitely was never fired from its rebuild 15-20 yrs ago by verle stevens racing engines (I just found out he built the engine for the champion 2010 lucas stock drag racing car). It was set up for 10.5-11:1 to run on alchohol, like someone guessed already on this board.

Although its a 052 block (with the small 2), I think its a yenko early ZL-1 block considering it has no numbers on it or winters logo on the front, and has press in freeze plugs. I read previous postings by ed cunneen on this site that yenko did some blocks (under license from GM using their molds) before he went to the yenko crest. Once I pop the front timing cover off (it is currently set up for a blower that never fired), I would not be suprized to find a yenko stamped number, according to what Ed posted.

It does have some some cast in numbers on the back side of the block, mirroring the casting 052 number location. It reads HRT CST. (probably foundry other than winters?).

After getting this thing, it is amasing how light it is, and would be great to put in my 61 vette.
