Pete,

Is the *Yenko* crest cast in the front, above the water pump ??? Forgive my ignorance here, but is that real ??? Kinda cool - NO REALLY cool if it is.

Hi Casey;
The block is a real Yenko casting. Yenko was making these blocks into the mid to late '70's primarily for the boat racers, we have also found some dirt track racers that purchased them as well. These blocks are more common than you might think, I have seen 4-5 of them within the last 2-3 years at local swap meets. I ran across a set of 074 aluminum heads this weekend at a swap meet, but like most they had been repaired. Also found a set of early '69 840's - $800, he took them back home with him.

Thanks Marlin !!

That's why I come to this site - the *buffet* of Bow-Tie knowledge I absorb is very cool !! (that and busting Rob and Pete's chops every now and again ....)

Thanks Marlin........and yet once again, I go away with a little more knowledge than I had this morning! So who cast them? Was Winters in charge of this?

To my knowledge, Winters still did the casting - the customer was Yenko instead of GM. I have some advertisements for these blocks from Yenko SportsCars Inc. where they say 'we are using the same foundry that produced these blocks for Chevrolet Motor Division and employ the original Chevrolet quality specifications.'

Here are some ads for Yenko's ZL-1 block:

Yenko was also working with Weslake Engineering in the mid '70s to get a set of aluminum, 4-valve per cylinder, hemi-heads for the 302. The ad they had worked up stated "580-600 horsepower: From a 302!" Pretty wicked looking heads (we've got some pictures of these things I will post later).
