Question

Another question guys (sorry)

How do I tell how many teeth my flexplate has? (without counting each one)

Do I measure the diameter or are flywheels one number and flexplates another?

I'd like to put on a high torque starter and want to get the right one.

Engine is a late 68 396 with TH 400.

Thanks for any and all advice!

Joe

Cool

check out your jegs catalog and they have cvr mini tourqe starters. theyll rund about $150 bucks but they will work with either flywheel and they are adjustable for clearance. ive got one on my 85 475 horsie small block s-10. its a tight fit in there!!! so it should be just fine for what you need

mcorry,

i have seen both in a SB car's. it depend's on the application, i believe all 350's and 400's had the larger flex plate. as for the smaller SB's i guess it bepended on the application and ranny. i belive it also has to do with the tranny bell houseing size, but i am not sure.

I had to replace my flex plate when I installed the 700r4. Mine was 153 tooth, just by chance I'm sure, and was being used with a 350 and a PG trans. I did find out though that the 168 tooth seemed to be much more popular in the parts books at all the major suppliers.

Joe, put your glasses on, get under there, mark the first tooth and start counting. Come on, I know you can count that high.

I guess I could get the neighbor kids to come over so I could use their fingers and toes!
How many kids would it take?
