What size Flexplate?????

I have a 69 suburban with a 350 and a 4speed. I will be converting to a 700r4 soon. What flexplate do I need to use with the stock starter. IE how many teeth?

I'm terrible with numbers, it's the big one. (168 I think)

Use the same size as your manual flywheel if you are going to use same starter. (14"=168 teeth--12 3/4" = 153 teeth.)

Ok yeha I figured out that it should be the same size. Im just too lazy to take a look since its not apart. I was wondering what came stock, so that I could get it and have it ready when I do the swap. Thanks for the help.

I went with the 168 tooth and a high torque starter. I recommend the smaller one though. I will give a little more room for exhaust clearance.

Get whatever works with your starter.
