Cam Help

This is a discussion on Cam Help within the Firebird / WS6 forums, part of the Vehicle Specific category; I was wondering if Comp Cam XER287HR would work with a stock 2001 Firbird Formula LS1? If not what else ...

    That's ridiculously huge if the specs are right. The big ass donkey dick cams I am used to seeing are in the mid 240's and low 250's and those are rare. It wouldn't work with a stock ls1 at the very least you need headers to support a cam with an intake/exhaust split that is so close together. They do make cams for stock exhaust manifolds that are on the tamer side. But most people are greedy

    That came is way to big. Also if you have a AUTO like me you will need a stall to get good use of a cam. I would say on a stock motor use something in the 22x range with 598 list and wither a 112 of 114 LSA. I am doing a 3200 and going for.a.Texas Speed Torquer2 cam.I also have full bolt ons including a.LS6 intake lt headers, and the rest of the usual goodies.

    Gear it up, get a good stall, and a helluva tuner and rock it. Already have had the "big vs small" cam debate, and in the end its what you want and nobody else.

    i just got my TSP 233/239 cam shaft installed yesterday. Its great, lopes big but it needs a tune. I honestly think it drives easier than it did with the stock cam. Definately sounds way better.

    I want a little lope but add some power if possible. why would the specs i gave be too big? I have never worked on valvetrain components before but just starting to learn the technical aspects. How are Lunati cams?

    would the valve lift have to do with that higher duration or does that have anything to do with it?
