i have some excess noise with some ticking which i believe to be the lifters... i called a shop and was going to order comp R's untill they told me 3 motors came back blown because of a lifter coming apart...3 of them!!!! i guess Comp wouldn't do anything about it. This has scared me some because i was planning on going w/ Comp R's. Does anyone know of a company that will stand behind their parts if something tragic was to happen? Like most of you I too have to much in my motor to just throw any old lifter or any part for that fact in. These will be going in the 383, so post url's I would like to get some bought ASAP.

 

I don't think any company is going to pay for new 383 if there lifter goes bad if that is what you are saying. But I know that people have had good luck with comp R's and if a shop had 3 cars where lifters came apart I would not use that shop. Just my .02

 

There is absolutely nothing wrong with the OEM lifters if you are going HR (which you do not specify).

hey rich..you think oem lifters will be ok in a forged 383lt4? im not sure how big the cam is gonna be ..but somewhere along the lines of a gm847.ported heads/intake. and i dont plan on spinning the motor past 6700rpms..(its gonna have a 200 shot)

 

Comp changed the comp R design about 6 months ago to correct the problems they were having. The Rs are a superior lifter for anything with a lot of RPM or spring pressure

 

i guess i will stick w/ the comp R's. The whole idea of 3 motors going bad out of the same shop just made me rethink things before i spend a dime. I do plan on installing these myself, just didnt know if there were any known flaw's w/ the R's.

Thanks for your guy's input!

 

I am using the stockers, actually the original one's that came with my motor. I am on my second block, fifth cam, second set of heads, fourth set of valve springs, and so on, and they keep on (not) ticking!

IMO you're asking for trouble when the little needles fall out of the roller and whammo. Not the fact that you are using stock lifters but the fact that you are using OLD lifters. I'm with you as far as relying on the stock lifters. They are very robust. If I had either high revs or high spring pressure, I would replace the lifters every 50K or with a rebuild.

 

Mine have about 30,000 miles on them. Mostly pretty easy street miles, believe it or not.
