there are a lot of stroker cranks but $$$$$, I have flathead cranks for free
I have its allot of work . I used a arc 175 stroker gear and machined a sleave to fit flathead crank had to machine aluminum race for crank seal on mag side . Lots of machining to crank to clear cam used arc clone stroker rod with weisco piston . Spent about a weekend clearanceing and fabing parts .has anyone tried a flathead crank in a pred, they work in an animal, might have to machine the bearings to fit.
