i bought an 85 302 that was originally bolted on to an aod. i wanna bolt it on to my c4 but i noticed the flywheel was to big for my c4's bellhousing. could i just take off the flywheel from my 250 and put it on my 302 and bolt it on to my c4?
No, you can't use the six cylinder flex plate with your 302. You will have to get a 157 tooth flex plate balanced for your engine.
