Good morning, Are all 1965 Buick 300 V8 cranks machined to fit a pilot bushing? Did the automatic models use same crank as manual models? What about 1965 Buick 300 V8 engine block, Did the automatic tranny cars have the engine block tapped to accept the "z bar pin? I'm asking because my skylark is an original automatic transmission car, and I will be doing the 4 speed swap. Thanks, Robert
My 64 Special was a factory 3 on the tree. I later put a 66 340 in it and that crank was machined for the bushing and the block for the ball pivot so, I would assume they are all machined for the bushing.
No, not all 300's are finished drilled for the pilot bushing. I've had many apart and all were rough drilled with a step and would require you take the stock bronze pilot bushing and have it carefully machined for a .0005" interference fit.
