1981 GMC 454ci flexplate tooth count?
Bone stock 81 GMC 2wd dually with a 454 and th400... Truck has headers and the stock starter is having trouble when warm. I have a powermaster mini starter but I don't want to put it on in case the tooth count is wrong on the flexplate..
Anyone know off the top of their head what it should be?

And not on a big block, 153 was on Camaro's and Caprice's IIRC, but small block only.

High compression engines use 153 tooth plates. My ZZ4 comes from the factory with a 153. I had to buy a BB starter to keep it.
