How do I measure my flywheel to make sure exactly what I have. It does have a 10.5" clutch that was run on it. The measurement between the holes drilled around the edges is 11.25". Does this sound right for a 10.5" clutch?
Just count the teeth on the ring gear to know which flywheel you have.
The 10.5" - 10.95" flywheel has 130 teeth
The true 11" flywheel has 143 teeth
The 9.5" flywheel has 122 teeth.
I do have an extra 10.5" flywheel for a SB 273-318-340 motor in garage if you want I could measure it if you would like....How do I measure my flywheel to make sure exactly what I have.

yep130 tooth flywheel behind a 440 doesn't make sense to me - the big blocks used 143 (I think) tooth flywheels, I don't think he would have had starter engagement using a stock big block bellhousing. It does sound though like you have the stuff you need to put together your small block set up.
