250 adjustable rocker arm pushrods?

Well-known member
I've now got an adjustable rocker arm assembly for my 250 & am looking at the pushrods for the swap. Classic Inlines has 2 types for the 250, non-oiling (P/N RAS-250-ANP) & oiling (P/N RAS-250-AOP). Which would be best for my application?
For right now I'm going to just install the adjustable rocker arms & pushrods, but in the long run, I have a different (solid lifter) cam I plan on installing. Any thoughts? Thanks,
Edwin
 
In the long run though, I'll be going to solid lifters. Is that going to cause a problem if I have the oiling type? Or is this one of those things where I can use either (oiling or non-oiling) with solid lifters, but I HAVE to use the oiling rods with hydraulic lifters? Or will I need to get new rods when I swap the cam & lifters?

Edwin,

I pretty positive that you need the NON oiling pushrods for either the Hydraulic or solid lifters.

Here's why. The oiling pushrods are for the roller rocker arms. If you have the eary sixties rockers that are the Ford stuff, then it's the non-oilers for you. The FoMoCo rockers get their oil through holes in the shaft and holes in the the rockers themselves. The roller rockers get their oil through the pushrods.

Call Mike at Classic inlines and ask him for sure. If I am wrong, please let us know so I can correct my data.... It is always good to learn what is right.

If you FoMoCo rockers are a "used" item... read the sticky I did on cleaning rockers and shafts... ah heck - read it even if they are new, then you'll know where the oiling holes are.

I re-read your post and it is not clear which type of rockers you have.
 
"not clear which type of rockers you have"

Hey, good point, suppose I should add that info! :) The rocker arm assembly is off of a 1964 144, so its one of the earlier ones. I haven't had the chance to tear it down & clean/inspect it yet. I'm not planning (at least not any time in the near future) to use roller rockers, so I don't think that'll be an issue. I do deffinately want to pull it appart & have a look at it, as I have a couple of these assemblies & at least one had the shaft upside-down... :roll:
So, NON-oiling seems to be the way to go?
Thanks for all of the responses.

You will need special length custom ordered pushrods. The adjustable rockers you have require a cup end on one end of the pushrod to fit the ball end adjuster screw on the rocker. Non adjustable rockers require ball ends on both ends of the pushrod. The matching pushrods off of an early 144/170 wil be short for your 250 because the deck of the 250 was raised to accomodate the longer stroke.

I have read that Ford FE engine pushrods are the proper length. I got my rocker built by R.A.S. . they are accessible by phone if you call them and knowledgable on anything rocker arm related.

If the FE push rods are the right length, you will need the ones for adjustable rockers used on solid lifter engines.
 
63RedTudor,
The bottom line is that the rocker arm type will need to match up with the proper pushrod and lifter.
Stock type rocker arm assemblies (shaft mounted) both adj. and non-adj. use "non-oiling" lifters and pushrods. The oil comes up from the back of the head/block into the shaft and gets distributed from there.

Roller rocker arms use "oiling" pushrods and lifters.
Lifters can either be solid or hyd. Oil is pushed up through the pushrods and gets distributed around from the rocker arm.
