Dear sir If you're out here, and you still have your wits, I need to pick them on the subject of 'senior compact' cars. Specifally Pontiac & Oldsmobile. I need information on block sequence numbers on, well all 3 makes of the aluminum 215, but more specific to Pontiac ID's and Olds sequence block numbers. There's a code here which isn't revealed in the service manuals. Thank you for a reply.
Just a random question... if the code doesn't match up to the numbers the GM books show is it possibly a British block?
Why not just post up the info and question? Lots of information here that they didnt have to be the one assembling to know the data.
Block sequence numbers will be different between the Pontiac and Oldsmobile blocks because they were different and were not built on the same assembly line. Buick and Pontiac used the same block.
I worked on the development of those motors at Oldsmobile Experimental and have posted about them before. Pontiac used Buick engines, which had different cylinder heads from the Olds. BTW, the engine that went into production was the 2nd version. We had some early versions with high-silcon alloy aluminum that had no cylinder liners or valve seat. No problems, but not easy to machine back then. The '63 motors did not have cam bearings, cam just ran in the aluminum.
