I changed a 65 Buick over to a stick from an automatic in '71 and if I remember correctly, I had to get a special pilot bushing as the cranks were drilled different for the auto trans. I have 229 V6, 305 V8, & 350 V8 Chevrolet engines that had auto trans behind them and want to run sticks. (Muncie behind the 350 , T-5 behind the V6 probably) Is their something I need to check on the cranks for pilot bushings on these or are they all drilled the same? Also, does the 229 require an external balanced flywheel like some V8's ?
I dont know about the V6, never worked on one. I would guess though that they would be the same, since they came both ways from the factory. No clue about the balance. I've switched a few over, and dont remember anything special. I DO know if you dont know any better and leave out the pilot bushing, the input shaft on the trans wont last long. Also the torque converter wont fit in the back of the crank right if you dont take the bushing out, if there is one there. If you dont get a positive answer soon, I'll try to check a couple for you this weekend. Good Luck.
Don't know if in they're drilled differently or not. But you gotta pull the automatic out first any way so when ya get her opened up, have a look see and see what you'll be needin' (that's what I'd do)
Thanks, I had a OT El Camino with a factory 229 / 3 spd so I do know they used a stick with that motor, so I'll have to dig for more info on what to use....won't mention that set-up anymore as I know it's not really HAMB friendly even if it goes in a nice A roadster
The V8 doesn't need anything to it other then the bushing and flywheel/flexplate, if I remember correctly. Not 100% but I think the V6 Chevy is the same (229 is Chevy only, 231 is a BOP). I've seen many a/t cars with rebuilt motors that still have a pilot bushing in the crank.
