Any one running a stock clutch with 39.5 boggers the trans is a T18, Im just wondering how the clutch will hold up, Im thinking about running a centerforce clutch but dont want to if stock one will hold up . thanks
My buddy has a 78 with 44" Boggers. I think he's running a stock clutch. He's got a 400 though and it uses a 12" clutch. The 351M used an 11" clutch. Don't ask me why, the engines a basically the same. Ask this question on www.projectbronco.com theres a bunch more guys there running manuals with big tires.
