I need help finding out what year and motor I have in my 1937 Oldsmobile F37. I know it’s not the original motor.
casting # is 408004-2, the stamped # is T77429 and the head casting # is 408009-3. It is in need of rebuilding and need more information on the motor if possible. Can anyone help me please.
It may not be the original motor .
But it is either an F37 or F38 engine according to those casting numbers .
Both F37 & F38 engines are 230 cu in .
Bore 3 & 7/16 Stroke 4 & 1/8
