Smith Machine Ceramic llifters...
 

Well, after waiting for nearly 2 months, cant get SMith Machine(Schubeck style) lifters for my Pontiac... I guess they are having problems getting them done, by whoever is doing them. So , i guess im gonna go with a regular steel lifter...ANy suggestions? For E or F/SA 400/330HP Pontiac....

Trend Tool Steel. They do have a limited travel model that passes NHRA tech for a hydraulic lifter in Stock.

I suggest at least a P55 lobe lock cast iron core, and nitriding.

Will check into them... Probably cant put them on a used cam?

Cliff Sherman tool steel limited travel as well

Brent, I was told with a new cam, You break in cam with smith or schubeck lifter, then change to tool steel lifter, I think you would be ok on used cam, but i don't build my motors. Tom

To my knowledge Trend does not make a Pontiac lifter. Pontiac lifters are the same diameter as a Chevy but Pontiac ones are taller. Putting a Chevy lifter in a Pontiac can cause the oil gallery to become exposed at the top of the lifter when the lifter is on the base circle and or the lifter oil groove to become exposed on the bottom side. I can’t remember which it is, it’s been a few years since I decided to see if Chevy ones would fit. I would just use the Sherman lifters. If you really want to use ceramics I have a used set. I quit using ceramics years ago.

Hey Bill, in your opinion, is there much ET between the 2? Im planning on being in the 6500 rpm range...What about spring pressures? I might be interested in the used Ceramics...let me know what you need for them, and if they need resurfaced.... Thanks, BRent

Guys, if something is not in a catalog, pick up the phone and ask. It's not that difficult! PPP just made me a set of AMC TS lifters and there were none in the catalog. I just sent them a lifter I wanted copied and in less than 4 weeks had a set. Didn't cost extra either. Now it's available for everybody.
If I sat around looking at catalogs for availability while building an AMC, I'd never get it done.

Brent, you are so lucky you did not get those sm lifters. Jeff is right about PPP listers. Sm lifters destroy engines! Sad but true. Until they improve quality control, tool steel is the way to go.

Hey Brent X 2 on the Shermans have well over 100 passes on mine no issues !!!

Re: Smith Machine Ceramic llifters...
 

Used cam or not with a new lifter using a good BR fluid for a few passes will not hurt one bit and will make make you feel a little more at ease as well. Gibbs makes two different BR oils and works fine IMO.

Re: Smith Machine Ceramic llifters...
 

Is a Sherman lifter just a limited travel stock lifter? I guess you have to cut way back on spring pressure with those?

Re: Smith Machine Ceramic llifters...
 

I can ask them about that. I'm sure they can move the oil band if needed. They can probably make them taller, too. The price is reasonable enough that the upcharge would probably be as affordable as most anything custom.

Re: Smith Machine Ceramic llifters...
 

I`m pretty sure the only difference between a Pontiac lifter and a Chevy is the placement of the oil band.It`s higher on a Pontiac lifter,you can get away with using a chevy lifter as long as the cam doesn`t have a small base circle.

Re: Smith Machine Ceramic llifters...
 

As Todd Hoven asked, will i need to run 130-ish on the seat? And what roughly , do these run, cost wise? They may be the way to go...do they lash, like a Schubeck? or do you preload them, a little?

Re: Smith Machine Ceramic llifters...
 

Jeff, I understood SB Chrysler (pushrod oiling) are the same lifter. That's what I run in my 6 cylinder.

Bill ,

PM sent.........

Re: Smith Machine Ceramic llifters...
 

Brent, I would suggest a phone call to them and talk with them about the do and don't with their lifters he will talk with you and then you can decide what your comfort level would be with adjustment, spring psi , etc.
