I recently acquired a couple NOS sets of Chrysler Marine 440 hydraulic lifters. I'm assembling a 440 with a Comp XE262 cam and the lifters that came with it. The cam/lifters were manufactured in 2006, which seems to be about the height of lifter/cam failures. Just wondering if it makes sense to use the NOS Chrysler hydraulic lifters instead. The were likely manufactured in the early to mid 70s. Thoughts?

Id run the NOS ones. I have a nice set of Comp lifters. I cant use them because in the instructions it states they have to be ran with adj rocker arms even tho they are hyd. The snap ring is larger in diameter and may interfeer with a larger diameter pushrod. Especially in a SB because of the pushrod angle..


I am truckless..

Bummer you can't use them. I won't have any issues with that since I've got adjustable rockers and 5/16" Smith Brothers pushrods.

I've read on the subject extensively, and it seems that the quality of lifters could have had something to do with all the flat cams (in addition to the oil additive issue). Using these NOS Chrysler lifters would certainly seem to insure that the lifters are quality made with good materials...

What lifters are they ? unless you have some larger than stock pushrods on your non adjustable rockers there shouldn't be a pushrod to lifter issue. Now if the lifters are the Pro Magnums then that is the reason for adjustable rockers because they want to be run with almost no preload (.002 lash ???) and you can't get that without some type of adjustment.

You could run adjustable pushrods instead of adjustable rockers if you are set on running stamped steel rockers wit hthe Pro magnums ...

I use old stock lifters all the time when I can find them cheap--I ALWAYS soak them and disassemble each unit--clean with fresh thinner or suitable clean solvent and out them back together with a little WD40--you do not want any solvent left in the lifter--you wantthem where they will compress so you can set preload right before you prime them up--older units are always sticky inside with congealed rust proof etc
Most all of these lifters have the dark grey bottoms--I like that--the newer units all seem to be from Johnson no matter the price you pay or where they are bought from--Morels for rollers forever! Scorpion and others get the same lifters and polish the crowns--I have had good luck with them in race applications though I only do flat tappets for street anymore--Good Luck!

Thanks for the reply. I guess I can't really go wrong using the old Chrysler lifters...

I have a stock Chrysler original lifter that came out 1973 400 engine. I also have a brand new Johnson Hylift standard duty lifter so thought I'd take them apart and compare.

On the right we have the Chrysler original part number #3004647 which is listed for 1968 though 1975 B/RB engines.

On the left we have the Johnson Hylift standard duty lifter part number #B-2011. The date on the Johnson packaging is 04/19/05.

Compare the position and size of the tappet bleed hole as well as the overall length of the tappet body:

Next we notice the oil feed hole in the plunger cap on the Johnson unit but not OEM Chrysler unit:

The complete assemblies laid out side-by-side. Notice the Johnson lifter has a bleed hole in the plunger while the OEM does not. Also, the Johnson unit has four hole disc between the plunger and plunger cap, an apparent oil flow restricter to the push rod feed hole in the plunger cap.

AMC uses the same size , .904, lifter as Chrysler and AMC's pushrod oil , that is the reason for the hole in the pushrod seat, most of the companies that sell lifters have the same part number for Chrysler and AMC .

Interesting. Learn something new everyday.

I'm also curious if the size and placement of the lifter body bleed hole affects anything one way or another?
