I recently acquired a merc crank for my 8BA flathead and I'm looking for the truth to piston requirements. In reading posts to this and other forums it seems more of an opinion than fact that you must run merc pistons with a merc crank. Does anyone out there know the truth? Just being an average Joe resurrecting a flathead for my '53 F100 I'm looking for the most bang out of my buck.
Thanks in advance for your advice and knowledge - Bill
The Ford and Merc Rods are the same the difference in the lenght of the stroke is made up by the rist pin placement as stated above.
If you try to use the ford piston with the merc crank its gonna get ugly quick. If you try to use merc piston with a for crank you get abot 2:1 compression
