Flexplate interchange question? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**Joesjunk** · 01-13-2009, 03:45 PM

Is the flexplate for a 396 big block the same as for a 350? I have a good one on a 1969 396 block and need one for a 1972 350 motor.

Thanks!!

Joe, yes it should be the same flexplate, cant remember if its 168 or 153 tooth but I do know one of them does interchange.

Joe, No I didnt end up getting the truck that I wanted to do the body switch on. I'm going to convert my C/30 frame to 4X4, but I already have the springs and hangers to that one. I am needing a nice 71-72 front bumper if you have anything.

No good 71-72 bumpers right now.
