Does the transmission bolt pattern remain the same for most GM Small block engines? Got a '66 w/a '70 Olds 400
Ok now I am confused but good......1970 model Buick,Olds,Pontiac transmission will not bolt to a chevrolet, the bolt pattern is different. Maybe something has changed in the later models , but back then the pattern for at least the automatics were different. A automatic transmission that would bolt to a 69 model Olds 350 would also bolt to a 70 model olds 455, but a chevrolet automatic transmission would not bolt to either. Butch
