From: LT1 land...the "409" of the 90s!
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?

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?

Yea Im with ya on that barryI think companies are just confused however I wonder if the comp lifters are made for the lt1 specs or ls1sI assume lt1 because they state for standard chevy smallblock on summit

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

just one of those things i guess. thatsnk for letting us know what you found out. personally unless two parts have the same part number im not gonna use it for an application that the manufacturer doesnt say its for.
