Pilot bushing

Back in 1975 when I got my 68 340 GTS, I pulled the engine, rerung, and new bearings, HV oil pump, Hemi grind cam. I knew enough to put a new pilot bushing in it. Went to the local parts house that knew what they were selling, and got a new bushing. It would not fit, I took it back-they said that's the right one. That was back before everyone knew a machinist. What to do? Put a pair of heavy cotton gloves on, put the bushing on my index finger, and let it spin against the side of the grinder wheel. I checked several times till I got a nice tight fit. I figured the front shaft of the 4 speed was wore enough, so that it wouldn't have to be perfect. That bearing is still in the 340 to this day. So my original 68 340 had the smaller bore from the factory and the parts guy might have not looked down at the footnotes at the bottom of the page. So, I needed the .915 bushing, I was only 18, I didn't know there were

All the 340 cranks I've seen were all machined for a bushing. Maybe the crank is out of something else? Rather than hone the hole and cut down a stock bushing, I think I'd just get the Magnum BEARING version. It fits into the converter button hole instead. This is assuming that you aren't working with a '67 and earlier 273 crank. In that case, you have no other choice but to make a bushing to fit.
