=Are all gm transmissions the same bolt pattern? I have a 64 330 olds with the st 300 that is slipping in drive. So i think i want to replace it with a 350 turbo. I guess i will need some linkage for the kickdown then also? Thanks Phil

 

Yes Yes.... The Buick Pontiac Olds Cadillac share the same bellhousing/trans mounting pattern.

 

but what about chevy bolt pattern will they also fit?

 

no

 

Thanks I just scored me a good 350 turbo from a buick so all is well then.
