Okay so I have a 4V intake for my 54 f600 with the 256. I want to rid of the loadamatic distributor and put one in that has the centrifugal advance as well as the vacuum like they did in 57 and later. My quesion is will this reman drop into my motor? Buy Cardone Distributor - Point Type - Remanufactured 30-2808 at Advance Auto Parts

I know they used a different oil pump drive on the early ones, but im not sure if the 256 was the same as the 239. Also is that distributor in the link a centrifugal advance as well as vacuum? And if the shaft is different can I do any swapping to make it work, or do I need to change the oil pump?

This is the response I got from Ford Truck Enthusiasts.

"Yeah. That Load-O-matic is a veritable POS...... I used a dist from a MUCH newer 292 on my old 239 and installed a pertronix kit. I have a rebuilt 292 now

I think that dist does have centrifugal advance (also) if it is for a newer 272/292.

You might just ask Advance Auto. Or better yet, go to a NAPA or National Auto Parts, etc and have a look at the one they would sell.

Also, I would speak to the guys over at Y-Blocks Forever or maybe give John Mummert a call and ask him what advance "curve" is best for a 256.

Then take whatever dist you buy to an auto electric place that can put it on a dist "machine" and verify it is giving you the total advance you need."

What do you guys think?? And thanks for the help
