Will they both work in the LT1 in my 96z? There is only a $10 difference and the Pro Magnums say they rev higher without "pumping up". Sounds worth it to me in my LE2 setup. Thanks ---

 

I found one site that says they will work in a newer lt1, then another site that says a GEN 1 350 only, lol. Does anyone know? ---

 

I believe the 875's are what everyone refers to as the comp r's. The 850's are just a stock replacement deal. Apparently comp changed the design of the comp r's, and some have had problems with the new design. You need to talk to the people doing your heads and valve train and get their input as to what you should run with the setup

 

Did you bother to read Bret's sticky regarding the Comp R's (http://web.camaross.com/forums/showt...574):rolleyes:

 

Thanks guys, I didnt realize those were the R's ---
