Lifter identification

New old guy here. Can anybody tell me how to identify the steel lifter from the iron lifter? I've searched through a bunch of Y-Block Magazine back issues but can't find what I'm looking for. I had a cam, casting CABX, reground and used what I believe are the steel lifters (thin foot?) but right after start up it went flat. Issue #55 has some great info by Mummert about cams but I am still in the dark about lifter and cam compatability. Of course I never gave it alot of thought until this event. Yup, used molly lube, pre-oiled before start up etc. This may be a moot issue cause I will most likely buy new instead of reground next time but getting a little closure on this costly boo boo might make me feel better. Thanks in advance.

The 5120 steel lifter is EAA-6500-D.  The foot height is .14", the height including the undercut is .22"-.30".

The cast iron lifters are:

EAA-6500-C. The foot height is .22", the height including the undercut is .408".

5752073 or C3AE-6500-A (B8C-6500-A). The foot height is .186"-.188".  The overall length is 2.41".  The 60-64 parts book specifies this lifter for the induction hardened camshaft.

CABX cam, what was the original application, is that an induction hardened cam?  CAB cam is I/H.  Maybe went below hard case during regrind?  Just a guess.

Mummert's cam article in issue #77 of YBM, says the CAB-X is a 1964 cam, which should mean it's originally for a truck. Questions to consider; Were the Lifters reground also? Was it done correctly? As I understand it they are supposed to have a camber or crown on them. (someone here with direct knowledge, hopefully will comment further or correct me) What about a possible oiling fault ? What valve springs are you using? Is coil bind possible?.. Further that cam is a very mild cam & you might want to contact John Mummert & explain your dilemma. I'm sure he will have recommendations.

Thanks Dennis and Paul for replies. Cam was 249 degrees at .050, lifters resurfaced, Crower springs, guides machined for clearance, etc. I had a hard time starting the engine and I think the time spent cranking just wiped off the lube. One thing I am going to check on the five (five!) good lobes I have left is taper. Will post later on what I find plus exactly which lifters I used. Thanks, Dave

The lifter face should have a 50.00" spherical radius (approx), the microfinish is 8.  This is common to all of the above lifters.

Lobe taper is probably 0 deg 6 minutes - 0 deg 10 minutes.  Large end at front on 5,6,7, and 8 intake and exhaust, and large end of taper to rear on 1,2,3, and 4 intake and exhaust.

BTW, do the lifters appear to be original Ford, or are they aftermarkets?  Are they all steel lifters, or is there a mix of cast iron and steel?  

Regards,

Dennis

Drexel: Dennis may have hit on a critical item. Are your lifters ones that were made "off shore" say in the late 90s or early 2000s? If so you may have a set of "duds" which were made when a couple of old line lifter manufacturers ceased operation or making of flat lifters. The off shore ones are poorly manufactured in some cases & have contributed to numerous complaints of lifter/ cam failures. There are also oil anti scuff issues in recent times due to new EPA standards. That subject has been discussed ad nauseam both here & in various auto magazines. Most recently I believe in Street Rodder magazine, I think in the March issue(?).You might want to check it out. Actually "Ted" on this site summed the subject up well recently, so look back a few days for his contribution on the subject..

Yesterday I was looking at a 1960 NAPA parts book.  Y block lifters had a list price of 81 cents!!
