i have a oldsmobile 350 engine my casting number 557752 can anybody tell me what model oldsmobile it came out of.

 

No, unfortunately we cannot. That casting number was used on all 350 Olds blocks cast between 1977 and 1980. Those engines could have been used in the A, B, C, or E body lines within those years. It could also have come from a 1977 Firebird or other GM cars

 

okay thank you very much at the end of the casting number it says b so does that mean its out the b body line? so when i try to get part just tell them that i have a 1977 350 olds engine? thank you for your time
