Looking for a recommendation on a set of solid flat tappet lifters for a cam that I want to try. I thought that tool steel would be nice, but read the following thread and decided that they may not be the best.

https://board.moparts.org/ubbthreads/ubbthreads.php/topics/2402051/flat-cam.html#Post2402051

Application is a 440 iron headed bracket race motor. Cam is an old Lunati grind that I planned on using with Comp 928 springs.

Thanks.

What did you end up doing to get the oiling issues corrected?

Multiple things, main bearings worn, oil pump shaft bushing was REAL loose & ruined the oil pump , as of now I have 3500ish miles on it since the refresh & cam change.

I have been using Trend/Barton tool steel lifters. (they're a little different than directly from trend as the body has no groove/space in the middle)

The same set have been used on 4 different cams in two different short blocks. I use either Schaffer's or Valvoline 10-30 racing oil with no additional additives.

Currently using Isky 8205 springs.....I'd have to check my notes, but I think they're around 150# closed and #430 open


'86 Maple Grove KOS Mopar low qualifier......true street legal with no power adders.

NOS-used when losing since 1940.

I read that link posted above and my planned 3 year rebuild never happened last Winter so I lowered my shift rpm from 7000
To 6700 rpm and ran it for a forth year. Everything must be ok as it was still cranking out 6.0 passes. Still same EDM lifters and Penn Grade (old Brad Penn) oil and a zinc additive for extra insurance.

Thanks for the replies. I had my eye on the lifters from Barton, if they can be reused on cam changes I think they are well worth the money.

Yeah, well My lifters are still perfect & could be reused on a new cam, the old cam not so good.

I just read an add for tool steel lifters. I use the comp EDM lifters as well. Don't know who makes them for comp, but Hughes Engines and Bullet Cams sell a Johnson lifter with the oil hole as well.

I've made switch to a solid roller, but am still curious about what combination of cam treatment & solid lifter material is getting the up for street & strip use these days.
- Standard cast iron cam core
- Standard cast iron cam core + nitriding
- Standard lifter + EDM hole
- Tool steel lifter + EDM hole (assuming all the tool steel lifters have the EDM holes)

What I think I've heard between here and SpeedTalk is that tool steel lifters and nitrided cams are a bad combo. Now I'm wondering if tool steel lifters are simply a bad choice for long-term street use, even for non-nitrided cams.

What about standard EDM lifters and nitrided cams?

David Vizard claims a nitrited sft lobe has nearly the same friction as a roller lifter. Seems that nitrite is an efficient friction reducer. Never knew that.

IIRC, the nitrided layer is very thin. If that's worn through, then the softer untreated core is exposed and wears quickly.

These are the ones I used in my R3 small block. Curious to see how everything looks after 4 years.

All I know is I used Tool steel lifters with EDM on a non treated cast iron cam, That is how Trend & Howards said to do it, for the money I wasted I could have gone roller to begin with.

I did it backwards...I went from a solid roller, to solid cam with Howards EDM lifter (with the oil hole). With the oil through capability of the lifters (and oil through push rods), my push rods look much better this year. In previous years I was getting bluing at the push rod cups on a few....it was not good.

Your pushrods are oiled both through the rockers (shafts) and the pushrods?
