Hi Guys, this is my first post and Im wondering if someone would be able to help me with identifying a Chevy engine I was given many years ago.

I think its been stroked to 383? from originally a 350??

What Year is the engine? I think maybe a 69?

What does the S Cast letter indicate? Im guessing short

Why are the 010 numbers on both sides of the block?

The letters I can make out on the right front pad are Possibly U I T T (T on top and bottom lines) K L. Numbers - 509861 with a 1 also on the top line?

Was the harmonic balancer specific to and Cci?

Ha anyone seen the Block casting number facing the GM cast letters?

I have attached a photo with the ROUGH measurement using a plastic set of verniers indicating the stroke. Im guessing its 350 stroked to 383?

There are two different number Pistons? They are dome top forged pistons?

The appears to be a D stamped near the Oil filter?

I look forward to your reply and Knowledge base as Ive never had to try an ID such a mess before and Its left me scratching my head.

I would like to build it up to put in a 72 HQ 08 four speed Kingswood ute which currently has a VJ prefix 304?. I have also attached a photo of the VJ prefix and numbers on my current engine and would also like some assistance in pin pointing its origin as the VJ prefix appears to be a bit of a grey area.

Cheers Guys and thx in advance.
