i read somewhere that the crank is different on a later stick shift olds engine. maybe somthing where the pilot bushing-bearing fits mike
Many Oldsmobile engines used crankshafts that weren't drilled for a pilot bearing, so check your engine out before you're halfway through the automatic to standard swap; you may have to have it drilled by a machine shop.
As far as I know all 64 and up Olds flywheels interchange much like the vibration dampers. If the crank is not drilled supercars unlimited sells a pilot bushing kit that you can install in your AT crank that eliminates drilling the pilot hole. you just have to cut a little bit off the end of your input shaft. They will have more info on the different flywheels. www.supercarsunlimited.com Hope this helps.
yeah , find a flywheel from any late olds ( except from 64-67 330, early 400,425...internally balanced) small and big block flywheels are the same as far the pilot bushing...a few places offer one to be used with the undrilled crank such as **** miller racing, olds performance products and supercrs unlimited anyway, like dday said you may have to trim 1/8 inch or so off your input shaft when using the undrilled crank...not a big deal
www.catpep.com is the cheapest place I found to get a new olds flywheel for a manual transmission. Also after 1975 all olds cranks (at least for the 455's)were drilled for a pilot bearing. Good luck, what a pain in the ***
