Starter Help Needed

I took a staggered pattern out of my 1980-ish 350 and put a gear reduction in. At first I used the wrong set of holes and the starter drive missed the flywheel...moved it ove to the second set of holes and worked perfect...





OK, if you had all the original parts for the 64, then it had the smaller 153 teeth flywheel and the small, 403 style bell housing-------------WHICH WOULD HAVE USED A STARTER WITH A STRAIGHT ACROSS BOLT PATTERN.
Next, if you used the flywheel which was on the 350, THEN IT WOULD HAVE BEEN THE LARGER 168 TEETH FLYWHEEL. Soooooooooooooo, if that is what was used, how did you get a 64 bell housing to fit over the larger 168 teeth flywheel??????????
Last, for Chevy V8 engines, there are ONLY 2 SIZES OF FLYWHEELS: THE 153 TEETH VERSION AND THE 168 TEETH VERSION. PERIOD!!!
A starter with a straight across bolt pattern ONLY mates with 153 teeth flywheel. A starter with a staggered bolt pattern only mates with a 168 teeth flywheel. PERIOD!
Now, with all of that said, and without seeing the parts you have, I can't give you any better information.

If I remember correctly, the mid 70's 350 blocks only had a diagonal starter bolt pattern---I don't think they had a third threaded hole on the starter pad. If that is so, then the OP will have to install a 168 tooth flywheel and the larger bell housing. There's no other way around it. The diagonal pattern starter will not fit into a 403 bell housing.
