I have ran into this same kinda issue with the 194,230,250,292 blocks/Dist. when getting a Reman dist. With them being Bead blasted clean so many time the base becomes smaller which in turn makes for a bind on the oil pump when bolted down. Or forgot the gasket. You can try and find dist. shims Like they Use On the Vthings. this may help If that is How your getting your Bind on the dist to oil pump shaft. Hope this helps.}[oooooo]
