composite lifters

[jcsj]

I did a search found some info and was wondering if any one had tried them or had more info. thanks

I looked into the Schubeck (sp?) lifters. They need a higher rate spring and they cost too much. IIRC it was around $400 for a set. They are interesting, an wouldn't mind trying them if they really stop cam failures.. but I haven't heard enough info on them

I have a set of full ceramics Schubecks in mine, not composite. Bought them to reduce valvetrain weight and have the ability to change cams and NOT change lifters. They can be used over and over from cam to cam. Running 205 seat and 505 open. If I ever need to buy another set I will buy the ones from Four seconds flat. Talked with the man who actually makes them and he used to work for Schubeck. Most of the problems with the original composite Schubecks were a lack of quality control when it comes to tolerances. New ones out, are golden IMO.

Roller versions now available.

Yes, the price is high - for street lifters. The benefits are almost unbelievable considering the tappet problems the last few years. Reusable on any lobe, any cam, no ZDDP necessary, and on the rollers, no needle bearings.

I wonder which factory will use them stock first.

A set of these on a reground stock cam could almost be affordable compared to a custom billet roller - and you have less problems long term. Long run, they will get cheaper. Racers will move this way to reduce engine failure.

I'm sold.

I'm also looking into DLC coating stock lifters. Reputed to be the similar stuff, same results.

SIXPAK what is your installed spring height? thanks

[SIXPAK]

Not exactly sure on the number but it should be close to 1.650. Coil bind by the book was 1.115,+ .500 lift, = 1.615, turns out around .035 before coil bind. This gave use what we wanted for pressure very close to coil bind, just what the doctor ordered! Actual numbers from what the book said varied slightly on the springs as normal.

thank you SIXPAK there is a post on the hesco forum under '' another worn out distributer gear'' page five Lee Hurly as some insight on lobe width stock and after market. Also some info on the stock valve springs and their limitations. I think I will start a FAQ on springs I have some info and will try to put something togather in the next few days and I'm sure some of you have much more info to add.

Can you please post a link? I don't go to the Hesco forum but I want to read the discussion about cam lobe width.

Hesco has some good info and should be used for research on stroker/jeep mods.
