Hello and thanks in advance for helping a stranger who is asking for help.
I am a newbie, so hello moderator.
I know this is the welcome forum and I hope to get directed to a thread that is appropriate. Throwing it all out there and will copy and paste if needed.
I am attempting an Engine rebuild- my first. I think I can pull this off, but Im in a little over my head but I am determined to make it happen.
My first job is to identify the motor. The VIN number on the car is no help because the Engine was swapped after manufacture but before I bought the car. I never saw the car it came out of.
Looking forward to getting help here. The Engine has been in a 1979 Pontiac Firebird. I drove the car with the Engine running from 1993 to 1998. Drove this car when I moved from Mississippi to Pennsylvania. MS had no emissions- I was running dual exhaust with no catalytic converter. I didnt even try to get it inspected in PA because the car smoked (white smoke) before it heated up, ran hot, and from the sound it was making I self-diagnosed a bad lifter.
So, I pulled the Engine and disassembled down to the block- had some machine work done and left machine shop with a rebuild kit. Nearly got divorced when my wife heard how much that cost. The car has sat 18 years until I built enough love back into the relationship that I got the go ahead to begin any work again that may have a cost attached. Just had the cylinder heads rebuilt last month and the intake manifold hot tanked.
I read on a post on teambuick that the casting number on the block which is 1382201 seems to belong to a Buick in the 1967 to 1972 range. Casting number on the cylinder heads is B1233472.
I found the stamped number on the block which is 4OY176734 - I have no idea whether the second digit is a zero or an "Oh" - and I don't know what year or what plant made this motor.
I have written to Buick USA- who referred me to GM Media Center- who said to try Buick Heritage Alliance- which seems to be comprised of individuals who volunteer their time. The individual that described themselves as the expert I need has a dead e-mail link- and the next best choice hasn't responded in a week.
To further complicate things, while I was driving the car I found an intake manifold in a junkyard that let me change from a 2 bbl carb to a 4bbl. I completed this task with no research or close inspection at that time- the bold pattern matched up so I got a new gasket and threw it on there. Now that the engine is pulled and all my parts are cleaned up and laid out on a workbench I notice one of the ports on the cylinder head meets an area on the intake manifold that looks as if it was deliberately filled in.
The casting number on the intake manifold is B1249289-3 (there is also an H there off to the side a little bit.
While I drove this car the engine was a monster (in a good way). I have had many friends tell me to just get a crate motor but I am in love with this old Buick 350.
