Yenko motor?
 

I was cleaning out my fathers shop when I came across a big block with Yenko valve covers. How can I tell if this is really a Yenko motor or just a big block with Yenko stickers on the valve covers? Here are some of the numbers i got off the motor.
The Block: 140154, V1206MN, marked: high perf pass
The Heads: 3872702, E316, marked: pass
The Crank: W0792040

That casting # is for a 75-87 454 block. The heads are 1966 oval port heads. It sounds like a combination of parts but the stamping doesn't make sense unless it's a restamp. Can you post a picture of the stamping.

Guys dont know where Justin is I tried to contact him also with no reply..also looks like he found the Camaro site with his info and is asking around, I agree Jeff... and I asked for pics to determine what it really is...grab a number and see who gets the stuff if its worth dragging home.... https://www.yenko.net/ubbthreads/imag...lins/dunno.gif

Im in Utah, and the motor is about 2 hours from my house. I havent had a chance to get back out there to take some pictures yet, I'll try some time this week. Really im just trying to find out what it is, and if its worth selling or if We should just keep it.
