part number 875-16 are listed for the LS1 engine.
part number 850-16 are listed for the LT1 engine

Many people say that the 875-16s are the comp r. Why would all the internet vendors list them as LS1 specific. Arent ls1 lifters and lt1 lifters interchangeable?

 

875-16 are the TYPE R lifters.

 

875-16's is what i got, also known as Comp R

Any ideas on why companies list them as ls1 specific?

 

maybe its a typo... which vendor are you talking about?

 

on a completely different note (just thinking of type R) I saw a purple "GT-R"Mustang last night...

 

ya, to confuse the **** out of us.
I have ran into some parts that are for LS1 and LT1 but only give the part # in the LS1 section. Just have to call and ask. Most times they can't explain why, better off asking the manufactor

 

Easy way to explain it..

There's no such thing as a Type-R lifter... or IMO even an "R" lifter.. that's just what someone decided to call an 875 Pro-Magnum hydraulic roller lifter to get attention.

Nothing "R" about it.

 

Now Phil... you know that "R" = "R"oller, right?

And "Type-R" means serious fast.... if you see that sticker on something you might as well drive her home.

Then the 850's would be "R" lifter's as well

I think it was more a misnomer than people identifying a roller lifter, IMO anyway

 

I agree Phil... I was just trying to be a smartypants.

D'oh... sorry buddy, long day

 

It's all good Phil.

Have a cold one for me.... it's St. Patty's day after all and I am Irish.

*as good an excuse as any eh?*

I was told that when(if) the Rs are put back into circulation, they would have a different PN. This was also told to me by a Comp Cams rep over a year ago when he said "production will resume in a few months."

Either way, it'd be safe to assume that the PN will change because of a different manufacturer.

 

These companies all have it listed that way
