i'm running the Tsp 228R right now (228/228 588/588 111Lsa) it a great street cam but i want something thats gonna make a lil more Hp n TQ. i'm considering something in the 232/234 6**/6** range. what would be a nice step up from what im running now. also i plan on putting a dry 100shot on it this winter so keep that in mind. car made 417hp/399tq

thats pretty nice power as it is... wouldnt you just be better off putting better heads on it?

Cam swap not worth it IMO. Look for power elsewhere.

im still running a 10 bolt so a rear is next on my list b4 heads

so stick w the 228 n hit it w a 100shot looks better?

id do a rear b4 adding anymore power personally, do a rear, then heads

It ought to have an insane pull with that shot. I dont think you would hardly feel any difference after swapping cams, hence why I think your money is spent better elsewhere. You are already making great power for cam only.

what he said.or get your heads ported if $$ is on budget if not go with TFS heads and hit it with n2o.and then gotta worry about your 10bolt.thats when the 9in.comes in.

243 heads

If your adding a shot of N2O you might get away with a set of 317. They have larger chambers 71.6CC to be exact. The 317s have the same valve size as the 243s even though they are made for the truck line. The flow numbers are dam close and the 317s actually outflow the 243s through the mid range, and getting them to flow like 243s up on top should be very minimal work. I am sure that the 317s would be good, you will drop compression to about 9.5:1.

maybe i'm slow but why would you want to drop compression for a small shot like that? i'm under the impression that nitrous loves compression buy i've been wrong before

You where asking for heads to use and I gave you a choice of what could be used specially depending on the fuel available. It depends on the fuel your using also the engine. N2O can be used with engines as high as 15:1 compression and as low as 9.5:1. The higher compression the higher octane fuel your going to need to make sure you do not have detonation. With N2O with a lets say middle of the road compression 10.5:1 it would behoove you to use 100 octane as minimum octane. The less compression you have you can run N2O with less octane fuel, and less retardation of timing (ie 91,93 no less than 91) with detonation being less prevalent. If I am wrong some one will help me out or correct me out right.

I was thinking of using N2O myself (150 ws) and the guy who sets up N2O in my town told me I would have to run a minimum of 100 Octane any time I wanted to use it, and I am running 10.5:1 compression.

Do NOT swap heads that will lower CR, or do anything to lower your compression, unless you plan to go FI. Compression is your friend when it comes to making power and torque, especially so in a NA setup.

I ran 11.34-1 CR for about 3 yrs and I never ran anything but pump 93. Many people run 11 to 11.5-1 CR on pump fuel.

When you spray it, you can dump some race fuel in for added safety, but with a small shot, the correct heat range plugs, and tune, it's not a necessity.

I plan on doin heads next winter so for right now I'm looking
to go w a small shot of spray, is the 228 spray freindly cam or do I need to go bigger that mite be more n20. Freindly. Like said I'm only goin w a
100 shot bc I'm still on stock bottom end

You do not need a nitrous specific grind unless you are spraying a BIG shot. Like 250+. All cams will work fine with the juice with a small shot.

I would look into a set of AI ported 241's! A guy on this site with an o4 gto m6 put down
417whp with the STOCK cam running those heads.

If I'm goin to go through the hassle of putting heads on it, I'm goin to go w afr or tfs Heads, not stock milled n ported heads, what am I gonna gain 15whp or so. Not trying to knock stock ported heads but they not
what I'm looking for right

you can also get nice stage 2 ls6 heads for a good price from TSP, dont leave those out. the 5.3s and ls6's make good power too
