I bought a motor from a shop, and I was told it was a 1970 250 truck motor... I finallt got it into my car and could not get the starter to turn the motor over. It sounded like it was hitting right into the flywheel. I tryed shimming it with no success. I could not even get the dowl in there. When I tighten the starter down it does not look like it is sitting right either. So I pulled the motor and the teeth to the stater look like they are sitting in the teeth for the flywheel. Is there different size starters for this motor? The one that I have has the parrelel bolts, just like on the motor. I have had a horrable time with this motor can any one please help...
