Hi and thanks to all for your help and advice with my '63 Nova for the past several years!
I'm having a problem installing a Muncie M20 in my '63. It has the original 194 L6.I have had a Powerglide and a 700R4 and am now putting in the Muncie M20. At the suggestion of my friend who is helping me with this project, I got a pilot bushing NAPA part# 27MP0028. He likes these non-magnetic sintered bronze pilot bushings as they are like the original ones in GM manual transmissions.The OD of the pilot bushing that came with my clutch kit and the one from NAPA are identical, but they are both too large to fit in the end of my crankshaft by about 40 - 50 thousandths. We could turn either one of them down on a lathe to correct the size but we are wondering if there isn't a cleaner, simpler solution. Also if we end up putting them in a lathe to make them fit the crank what is a commonly accepted interference fit between the bushing and the crankshaft.
We are wondering if this has anything to do with the fact that this 6 cyl has always been connected to an automatic trans from the time it cane off the assembly line until now.
Thanks for any help
Mike
