what is the correct engine block for a 68 yenko camaro?

Depends on the build date of the car itself. Early 68 427's (up to January, 1968) used the 3916321 casting. After this they went to the 3935439 block. Check the build date on the car to decide which block you need...

thanks for the info as that is the block i have but i just wanted to confirm it was correct.what about head numbers?

Cast iron: 3919840
Aluminum: 3919842

Of course, the numbers I posted above and here, are for the high horsepower cars. Yenko also sold lower horsepower cars and bone stock configurations as well. Just because it has "Yenko" on it, doesn't necessarily mean it's a Yenko high horsepower car! He offered 427 conversions in different horsepower ratings, depending on what the customer wanted and what he/she was willing to pay!

The other thing you have to keep in mind is that in the late 70's yenko Cameron's were destroying everything in their division in car races and at one time were not allowed in that division anymore. So racers with Yenkos would garage their camaros, pull parts off the car and add them to whatever they were racing. This caused a good number them to go on sale near race tracks missing parts.
