Ford crank Merc heads
I just finished rebuilding my flathead last week. it has a stock ford crank and mercury heads. my question is should i had installed a 4" mercury crank? or will it be ok the way that it is?
Welcome to CHR. I think that you need to hook up your vacuum advance. At part throttle when cruising you have less air and fuel in each cylinder, and the air-fuel mixture is not as densely packed...
