67 440 Lifters & Pushrods

[69L48Z27]

Doesn't seem to be a lot of data out there on pre-68 440s when it comes to lifters. Comp has a footnote that pre-68 gets a 824 hydraulic lifter vs 822. Looking at specs, it looks like the pre 68 lifter is longer .1". My engine has an old Erson 140H cam with aftermarket lifters and pushrods. These lifters are the short ones, or 68 and later ones.

I assume the difference between the two might be pushrod length.

Do I keep the short style lifters or go back to the long ones? These pushrods are non oiling, no hole. Should I replace them too? What is the stock length pushrod for a 67 HP 440?

Engine is a stock rebuild. Thx!

I thought the difference was a 1/4" push rod tip for the '67 and down and a 5/16" push rod tip for a '68 and up.

Your on to something there, I just looked at the aftermarket pushrods and the ends are not same size. 1/4" and 5/16", never realized that.

Still wonder why Comp shoes two different lifters thought.

If I'm sticking with stock valvetrain should the pushrods have an oiling hole? These pushrods are about 9 3/16" overall length.

Whatever you do make sure you have both early lifters and pushrods or later lifters and pushrods don't mix and match don't ask me how I know.
