Trying to get a later model 302 (summit atk 059-hp79m) in my 75 mach1, what flywheel do I need that's 50 oz and fits the small c4 bell housing? The one that comes with it is 164 teeth and is almost 14 inches the original has 141 and 11.9 inches

You'll need to take your flex plate to a shop and have it rebalanced. I don't think there's a 50 ounce flex plate available anywhere.

Sorry to be the bearer of bad news, that's just our reality with these cars. I did do some digging yesterday, Art Carr used to make a 50 ounce flex plate for the II, but he's long out of the business and it didn't appear that the new owners offer anything like that. Sorry man....

No problem thank you for trying, had this car 30 years now and still just as hard to get parts as it was back then.
