ZZ4 starter question
Embarrased to say, I don't understand how this starter replacement situation works.
.Can I use my original 1969 350/300 Starter for my ZZ4 motor?
I thought I could use the OEM starter that was on my 1969 SB Corvette on my new ZZ4 motor. My 350/300 with automatic has a 14” flexplate (168 tooth) and the ZZ4 has a 12 ¾” flexplate (153 tooth). I read (in the Summit Catalog for instance) where (some) same part # starters will work with either a 153 or 168 tooth flywheel. Yet OTOH I see advertised, different starters for 153 or 168 teeth units. In the former instance, how can the same starter work with both of these flexplates when one is 1 ¼” difference in diameter?

Several options: Put a different nose on your stock starter (did that years ago), buy an aftermarket starter (eh, no thanks), or buy a used later model gear reduction (lightweight!) Corvette starter (did that).

I also have a ZZ4. I seem to recall that the block will accept either starter (two sets of mounting holes)... Its been awhile so I may be mistaken. I bought a SBC starter from NAPA, worked perfectly.

If you change flywheels you would be able to use the old starter. I am not sure if they have a smaller flywheel though.
On a different note, if you had a 4 speed manual it is possible to keep the stock starter. I did that with my 71.

Bull nose starter .
I will probably only add to the confusion, but here goes:
Bought a ZZ4 that came with a hi torque, small starter. It went onto a flexplate for an automatic trans.
I am now in the process of removing the automatic and converting it to a 4 speed -original BW Super T10 trans, using a flywheel for an 1986-current ONE PIECE REAR MAIN SEAL. I inquired at Pace Performance -supplier of the ZZ4- they sent me a "1967 Corvette style" starter with a bull nose on the shaft end. They stated the small hi torque starter would not work on the new flywheel. Make sense?
I dont know the difference either as both the flex and fly wheel are 164 tooth ,and both are 14 inch wheels..... But thats what I was told by them.

My OEM 350/300 starter bolted up to the ZZ4 with no problems but, this does not necessarily mean it will crank it then- correct?
