I'm working on putting a 351w into my comet. the 351 is out of a 84 ford f-150 the comet is a 76. i've been looking for a 50oz flexplate that fits a c-4 trans, do they even make them? i have the small bellhousing and the flex plate off the 351 doesn't fit the bell. i think what i need is a 13.3in. O.D. 50oz, 157 tooth flex plate for a c-4 converter
The flexplate off of the 351w is probably a 164 tooth. all 351w are a 28 ounce. So what you need is a 28 ounce, 157 tooth flexplate.
