Funny thing. Back around the 1977 time frame. Pontiac was running short on the 400 engines. They started putting 403 Oldsmobile engines in their cars including Trans Ams. Remember a lawsuit and they gave those owners a check for that. Can’t remember how much. Probably 600 or so. Back then Pontiac motors were all big block engine. Even the 326. Another funny difference in Chevy and Pontiac is the mechanical fuel pump drive on Pontiac is an egg shape metal wheel that bolts to top timing gear. Went to a dealer around 1983 to get one. Figured mine was old and worn. Parts guy was adamant that it drives off of camshaft. Told him to look in his book
