It isnt necessary but I did one block with bushings and the one in my Rampage isnt bushed... if your talking the EDM hole to feed the roller, the AMC ones dont have that hole but they are PR oiling... the bushed bores will help if you bend a PR and the lifter pops out

Maybe they are putting the EDM hole in the bottom.. but the stock MP AMC roller lifter didnt come that way EDIT When I was building my 416 I was going to use a set of AMC rollers but I wanted the EDM hole in them for lower RPM idling on the street... at the time Brian (on here) was the only one that made a EDM roller with the PR oiling so I went with his... he was doing the design which he did for Comp cams(if I remember right).... now there are a few companies out there that do the same set up Last edited by MR_P_BODY; 02/20/13 01:12 PM.

They are from Comp and they have the oil hole in the bottom of the lifter plus they have the small hole in lifter cup and these are solid flat tappet lifters. They look to me if I had hollow pusrods they would oil up thru them. But I have solid pushrods and oil the shafts the normal way with my little EZ heads. Course they are in the eng now but I am 99% sure I remeber it that way. Ron

The EDM is for the cam lobes and lifter face lubrication. The pushrod oiling is totally seperate issue from the EDM portion. The pushrod oiling is pressurized from the clearance in the lifter bore, thru the lifter, and up into the pushrod, if you have that type of rocker system. Youi can use the AMC lifters with standard ball/cup type Mopar pushrods, or with oil thru Chevy type pushrods. The solid ball in a Mopar type pushrod will just restrict the flow out of the lifter.

Thanks for the info. That is what I was looking for. Just so you know... NEVER did the MP or stock AMC lifter have the EDM hole to feed the roller face... the AMC lifter had the hole to oil the PR... so if you have the bottom EDM hole it was put in a lifter afterwards.... the EDM process didnt exists back when AMC was around... so if its a AMC type lifter its a aftermarket lifter that has the PR holing hole and had the EDM hole added(or they made a new lifter that has the PR hole and EDM hole) EDIT MOST guys call the push rod hole type of lifter a AMC lifter(which in all rights was) for the mopar family engines Last edited by MR_P_BODY; 02/20/13 11:20 PM.

My point is that I have read that at least some of the BB mopar lifters that have EDM holes are AMC lifters,(taller cup height, meaning a shorter pushrod is needed) due to the height of the oil band, in order to oil the EDM hole. What I didnt know was that these same lifters would push rod oil. "Im supercharged, might explode in your face"

I just wanted to have PR oiling and they worked fine... on this last build(416sb) I wanted the EDM hole to the roller face so I could drop the RPM on the street and still have good oil on the rollers

An EDM hole is in the BOTTOM of the lifter , the hole in the pushrod cup of an AMC lifter is STANDARD issue , is it EDM'd in it ?? I have no clue . When EDM lifters are talked about it's lifters with ADDED holes in the bottom of the lifter ... Then Raff throws in about roller lifters and the OP still hasn't even stated the type of lifter he is asking about other than an AMC style lifter . Not that it matters at this point I guess

I am talking ROLLER lifters... the AMC roller lifter had PR oiling for years... but they NEVER offered the EDM hole to oil the roller face... that EDM hole never accrued until the last few years (and AMC NEVER had it in a stock roller lifter)so I hope I cleared up what I was talking about... but the EDM hole only started about 3 years ago in MOST lifter weather its a flat tappet or roller lifter

I had my block bushed for .842 lifters and am using SBC edm lifters...That 904 diameter stuff is over rated. JK... I have a set of the howards BB mopar EDM solid lifters...which as Ive said at least once...are actually AMC lifters (not that it makes a rats behind)...based on the cup height....oil band height...etc. "Im supercharged, might explode in your face"
