Hey all, In the process of putting a 49-53 flathead mercury in between the rails of my 32 ch***is. I am looking to do so using a Muncie 4 speed.. Question... is the Ford 239 flywheel the same as the Merc 255 fly wheel? I know the stroke is different, but i want to be 100% sure before i spend the money on a flywheel that accepts the GM10.5 clutch Thanks all
The difference between the Ford & Merc 8ba style flywheels is the clutch bolt pattern. Ford p***enger car '49-'53 would be 9 1/2" Long style pattern, Ford 1/2 ton '49-'53 truck would be either 10" Long or 11" long patterns. Mercury '49-'53 would be 10" Borg & Beck pattern.
So how would this play out if i buy the Centre Force flywheel that is drilled for the GM 10.5 clutch.. i should be fine?
If the Center Force flywheel fits the 8ba/Merc crank,you should be fine. Talk to Center Force & be sure.
The standard Chevy 10 1/2" pressure plate from '60s-'70s & probably more will bolt to the '49-'53 Mercury flywheel.
