Briggs Flathead crank swap

[jreid50]

Does anyone know of a crank from another engine that will fit in a 5hp flathead? looking for a longer stroke without the $400 price tag?

I think your gonna be looking into a dedicated stroker. Lunati forged cranks are cheaper, but arent as strong.

You not going to find any other small engine crank that will fit in a 5hp motor it don't work like that if it was a Chevy 350 you could use a 400 crank and have a stroker 383 but it don't work like that in Briggs land
