If you have the small flexplate ( believe its 12" vs 14" for the large) you need a starter nose with inline bolt holes, not the diagonal. If you block is only drilled for the diagonal bolts, you will need to switch to the larger flexplate and use the starter you have, with the diagonal bolts. I think the block should be drilled for the inline bolts also, if that is the case get a starter for a 307, all 307s I have had came with the smaller flexplate. Just verify the nose has the bolt holes inline, not diagonal..

That would be the easiest way. I had the same problem with my car. Didn't realize it until the car was back together.

If I were you I would just change the flexplate.

What I did was too much of a headache. I drilled the 3rd hole.

You may already know this but, to change the flex plate without removing the tranny try this trick: As you remove the tranny to engine mounting bolts replace the top two and the bottom two with extra long bolts. Remove the rear tranny mount bolts and drive shaft. Now you can slide the tranny back far enough to remove the torque converter and flex plate.

Try this trick, bolt the starter on you want to use with the solenoid off the starter. You will only be able to get the one bolt in, make sure it is the right bolt. Square the starter to the flex plate, push the gear out and check for engagement. Next using a tranfer punch, go down through the long bolt hole of the starter and mark the block. All the blocks have boss on the under side, but they are not all drilled. Drill and tap the block for 3/8 16 threads, counter bore the top of the hole larger just like GM did. Done. Bolt the starter on and the small flex plate will work. Just did one for this 60 vette I'm working on. I'm using the late model LT-1 starter, it only fits the small flywheel.

BUZZ,
I have to go with Wally on this one. I would do almost anything to keep from pulling the tranny. Even though I only have 4sp cars, the procedure for drilling the second hole would be the same with a bell housing bolted to the block.
I, personally have always been fortunate enough to build blocks with 3 starter holes, so I have never done this procedure myself. But I just can't imagine that it could be difficult at all.
Heck, I might just have Wally run over and do it for me!

This is a self defence move, changing the flex plate after all the goodies are bolted in is like slamming your fingers in a car door.

And one other thing, don't let anybody tell you there is a starter that will solve the problem, been there. The small flywheel had the straight bolt pattern, not the stagger.

If you use the LT-1 starter, you need to grind the mounting pad so it will fit flat on the block, the regular GM starter works without doing this. Use the brace, brace it, make sure it has the rear brace, did I say brace it!

Buzz, you might want to search down David's post on drilling/tapping. It was a nightmare for him )I think) and is not such an easy chore with the block in the car. look at his post and you;ll see what I mean. Wally and DZ are consummate pros with really good tools. Just a warning, could be a real bitch.
