you will need the truck pumps 8RT, they use the wide belt, have the motor mounts on them ,they move the belt groove out further for clearance. Do you now have a double groove pulley, if not you will need to change the pulley

4ford: The 8BA re-design required that the belt be moved forward in order to clear the posthole distributor design. So... you will have to change-out the pumps, crank pulley, and generator. In addition, the 8BA style right hand cylinder head had a provision for clamping the distributor in place, which is not present on your 59A style heads. The later pumps will work on your 59A, but your proposed conversion is hardly worth the trouble. Why don't you just go with an MSD 8353 front mount ignition if you want more spark? This will eliminate changing out all the above, and provide the same benefits.

Mike: Consider using your perfectly good 41 crab-style Ford distributor with a Mallory coil. This,combined with good plug wires and wire spacers (don't use looms), will give you a very serviceable flathead ignition system without having to deal with pumps, pulleys, ignition "boxes" and other expensive options. I ran this set-up for years on a 281 inch Merc with Edelbrock heads and 3-97's. Dan

Stroker, '41 was the last year for the helmet distributor. '42 was the first year for the crab distributor. JM

All: My Bad! JM is correct. I liked the crab style, as it was easy to wire, simple and compact. Apparently there were some issues with moisture due to it's simple cap design, but all in all it is great in any performance application.
