Hope someone can give me a little advice on this issue. I've had this car/motor since 1968. It finally got so tired that I rebuilt it. After a 30 over bore, I put it all back together with new pistons, same cam, crank, flywheel etc. Rotated the crank every time I put in a piston. With the heads on and plugs out, I can turn it over with by the crank nut. It's basically stock. I did put on a new ring gear and bought a new starter. When I got the motor back in the car, I couldn't get the starter to turn it over - bendix jammed in the flywheel ring gear. Long story short...took the motor out, tried the old starter - same result. Replaced the ring gear thinking it was the wrong one. Same result with both the old starter and the new starter. I've tried it with the starter/oil pan bracket and without it. Took the clutch and pressure plate off and tried to manually engage the bendix but still can't get it to work. I've never had a problem with flathead starters before but I'm flummuxed here. I'm sure I've forgotten other things I've tried but you get the idea. Any suggestions would be appreciated.
