Default LS1/LS6 lifters in LT1??

are LS1 & LS6 lifters the same? also, would LS6, or even LS1 lifters be an upgrade when putting in a cc306?

Not according to the old Part numbers(circa 1998) We have been using them back and forth for a while. I know you sell tons of them so I must be wrong but just what we found years ago.

Does Comp sell a different one for LS1 cars now?

Lifters are one of the VERY few parts inside the motor that is interchangable between LS/LT motors

Ditto. I know both the lt1 and ls1 guys use the comp R (875-16) lifters. So if the aftermarket stuff is interchangeable, then why wouldnt the stock stuff be.

you see, that's what i thought, that the LT lifters are different from the LS ones, but they are interchangable. so that's why i was wondering if the LS lifters are better than the LT lifters to use for a higher revving cam. also, i hear the comp r's(875-16) are a b*#ch to set, is this true?

The comp Rs are a little more touchy, but i wouldnt consider it a b*itch. You want to set the preload from like 1/16th to 1/8th a turn and that should get you really close.

The LT1 lifters from GM are different ~the (plunger)-cup is .075" deeper than a GM LS1 lifter,and the travel between the two (Gm) are also different.At which if using one or the other would directly affect the pushrod lenght!

I appreciate that,I have emailed my contact at COMP CAMS to see or too even learn how it is thier lifter will work in 1987 to present LS1.I am just confused with the fact that THE GENERAL is so much different.I also heard a long time ago that these lifters were the same?Any~probly beating a dead horse on this!

im wondering if its the spring rate inside the lifter. maybe it takes more pressure for the early style to push the plunger down. aftermarket could easily change that rate to something they feel is better and at the same time be suited for both engines. just a thought. im curious to know the correct answer to this as well

Well this subject can go on and on.I finally got to speak with MARK CAMPBELL @CRANE CAMS regarding this issue.hopefully I can relate this to who may care!The important dimesions on a lifer are the diameter of the lifter body and the position of the oiling band around the lifter body.Our bitch was how can a LT1 lifter be used in a LS1 application.Because the plunger and cup depth is different between the GM lifters.Now there are aftermarket people who have a lifter that works for LT1'S AND LS1'S through 99 yr!Aftermarket lifters such as the CRANE'S lifters will only work ok to about .610 lift.Recommended preload is .060-.080"! Incidently,GM and some other manufacturers run thier preload at .060-.100" on hydralic lifters.My last response was that the GM lifter (LT1)THE CUP,plunger is .075 deeper than the LS1 lifter.TRUE!This difference in pushrod seat position would necessitate ethier longer pushrods or adjustable rockers.YES~our findings state that a aftermarket lifter such as CRANE or COMP CAMS will work with the proper pushrod lenght and cam lift-base circle diameters.OH WELL!
