I have a 1969 c4 tranny and I am bolting it to a 1981 302 engine with the 50oz harmonic balancer. Witch 50oz fly wheel should I use.

Hi, Providing you’re positive the 50oz balance is correct (81’H.O.) and have the C-4’s Torque Converter, the 157 tooth flex-plates use a 10.5" TC bolt pattern, while the 164 tooth uses an 11- 7/16" TC bolt pattern.
Large Bell: 164, small Bell: 157. Depends on which Vehicle they were used in.
Those 146 tooth Flexplate’s were used in later, smaller Cars like the Pinto, Mustang II, Maverick.
Hope that helps!

Summit sells a large selection for the C4 / C-4 using either the 157 or 164 tooth flexplate with 50-Oz external balance depending on which bellhousing your transmission has.
