C2 1967 327 YZ or YS Engine Code Suffix

[Tom D.]

Working from memory here, which is risky at best.

Seems I recently saw a 1967 Casting date on a 327 block, and the Engine Suffix code was YS or YZ. Mr. Colvin does not list. Any thoughts on this?

I can dig up the casting number if needed.

Thanks in advance.

Tom------

Yes, I have a thought. Engine suffix code "YS" was used for 327 cid/220 hp engines installed in some 1966-68 Chevrolet trucks. So, an engine could easily have a 1967 casting date and 327 casting number with a "YS" code. It was never originally installed in a Corvette or other passenger car, though.

Re: Thank You Sir.

Tom,
You may be talking about one of the blocks in my shop that you seen on one of your visits. One of them is a 657 with a cast date of B 6 7 and stamped V0214YS and I definately pulled it from a one owner 67 pick up truck. Have accumulated some more "interesting stuff". Commimg this way anytime soon?
