Thanks now where would the casting number be located on the block...
Im new to the Buick

It would be on the side of the block on the driver side I believe. If it’s not there check on the passenger side. But it’s there.

I noticed you thread on your S-10 / 85 hot-air hybrid conversion. The engine compartment picture looks great. Post up some pics of the rest of the ride!

I also responded to your post about some serious engine knock on your first start-up. Sorry to hear your having trouble.

But I must ask........Did you take on this project on your own? I mean, did you have any friends or get any advise along the way from any Buick gurus? There tends to be a very expensive learning curve that comes with messing with these motors.

Stick around here for a while and a lot of us will jump in and give ya a hand.

If you are doing a total long block rebuild might wanna look into going 86-87 intercooled. Lots more power, little easier to work on and more parts available. Just a thought.
