G day all.
This is my first post and I apologise for straight away coming online with a question and please excuse my lack of knowledge but im running at a loss with indentifying my chevy block that I was given many years ago. I would like to put it in a 72 HQ wellbody that I have but would like to try and ID it first. Have also put up photos of the ute I would like to put the chev in and the present VJ prefix 304 that I would like some clarity on as the VJ prefix seems to be a bit of a grey area?.
I have been told that the knowledge base here is very vast and accurate and If someone is able to assist me in any way I would much appreciate it.
I have tried to ID the block and have spent way too many hours on the interweb and still can't narrow it down due to the huge and very ambiguous info surrounding the 3970010 blocks.
Im guessing that its been decked at some stage making the stamped numbers on the front right pad very difficult to make out as there appear to be two lots with the bottom ID stamps still just partially visible.
Was this block originally out of a Holden?
I haven't been able to remove the pan as yet but will down the track.
I think its been stroked to 383? from originally a 350??
2 Bolt main? going on the size of the plugs near the oil Filter
What Year is the engine? I think maybe a 69? or 68?
What does the S Cast letter indicate? Im guessing short
Casting number 2 near main block casting number?
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?
2 Timing chains?
Was the harmonic balancer specific to an engine size?
Ha anyone seen the Block casting number facing the GM cast letters?
I have attached a photo with the VERY ROUGH measurement using a plastic set of verniers indicating the stroke?. Im guessing its a 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 as Ive never had to try an ID such a mess before and Its left me scratching my head.
Cheers
Daniel
