def. headers before a cam. you have to let the engine breath before you can stuff a cam in there.

Agreed, go with some Header's before a Cam. I notice you dont have a Ported Throttle Body or upgraded to LS6 Intake Manifold listed for your mods. Those are also some good mods before a Cam.

mike991

Thanks for posting! what mod will make more RWHP cam or long tube
headers?

Unless you're looking at the TR CheatR cam, the headers will make more power. An engine is an air-pump. As long as the stock manifolds are choking the exhaust, it doesn't matter how big a cam ou put in, it'll be choked and make less than optimal power. AFTER adding headers the cam will make more HP.

Get the headers 1st.....then the cam.

mike991

Thanks man! my next mod will be American racing headers with cats,
then asp underdrive crank pulley, then cam, my goal is to make 400 RWHP
with these mods will I be there?

Dont forget LS6 or FAST Intake Manifold & Ported TB. You should definately hit 400 with all these mods.

mike991

I have the ls6 intake manifold, my speed shop does not port TB. he told
me you just get a couple HP with ported TB.

Headers will in no way make more power than a cam the cheatr makes like 35rwhp headers won't unless you have a cam already then headers add on . Exple

So if i install a cheatR cam in my car (see sig) I can gain 3 tenths with a tune?

If you are wanting to do both headers and a cam, then definitly do the headers first. The cam might give you a little more of a gain initially, but without headers you won't get as much as you should out of a cam swap.

Next I'll be adding the ls6 ported heads and will see how much more I pick up.
I already have the cam an intake so heads should top it off.

True, you only get a few HP from a ported TB but it all adds up in the end.
