390 adjustable rockers.........?
I would like to know if Ford adjustable rockers can be swapped for the non adjustable rockers that are currently on my rocker shafts.....or do the adjustable rockers use a different shaft.....
besides the push rods does anything else need to be changed to convert to adjustable rockers........?
Thanks

Yes, you can do this swap. In fact, the adustable rrocker gives you a little more valve lift as it's ratio is higher. The push rods do not have to be changed, but pushrods are cheap, put is a new set while you are doing this.

The pushrods will have to be changed David. The non adjustables have ball - ball type pushrods and the adjustables take the ball - cup type. The ball - cup type also tend to be a lot stronger on a general basis.
