I have been thinking about getting heads/cam on for my 99z and found on Texas-Speed a package with these specs:

Precision Race Components 5.3L Stage 2.5 Cylinder Heads Fully CNC Ported & Assembled With Stainless Steel 2.02" Intake Valves, 1.575" Exhaust Valves, & PRC Dual Valve Spring Kit with Titanium Retainers. Kit Also Includes TSP Hardened Pushrods & Your Choice Of Camshaft!!

So I've heard a small cam like the 224R would be pretty good pickup in power and still maintain driveablilty. I don't know which way to go on heads really though..Smaller combustion chambers like the 5.3 heads or larger and straight up more air flow. I am also going to put in a LS6 ported oil pump and double roller chain just to be catious about things, but my stock LS1 has 130k on the clokc and I'm wondering if I should just add these things, plus some headers/LS6 intake later and call it done or if it needs acomplete rebuild or what. I don't even know what power level I'd be happy with. It will be a strret car mainly. Probably driven at least three times a week or a little more. If I don need to go through the engine what all do I need to do? I'm not a compleet moron when it comes to engines, but I mainly just know the names of parts and know what they do, but not so much about how well certian things work toegther, I just don't have the experience. What kind of power could I expect out of a car with these heads/cam LS6 intake and headers?

I have 1999 blue M6 with 120K miles and am running Texas Speed ls6 stage 2.5 cnc ported heads and a 232/236 @112 lsa camshaft with stock gears. I have NO trouble driving this car 30 miles to and from work every day no matter what the weather conditions! It truely is ALL IN THE TUNE. What is your budget? for what I paid for all my parts...heads, cam, and all supporting mods. and after labor I could have purchased a turbo or supercharger for how much I spent....Dont rush into anything take some time and make sure you know what your goals for this set up is.

TSP's head/cam package is a great deal IMO. You should give TSP a call and see what they recommend for you. I wouldn't worry too much about the mileage on the clock.

sounds like for your needs the package you picked out would be great.

you could even step up to the 228 or 228r cam for a little more power but almost no loss in driveability or reliability.

either head will make great power. i would think with a smaller cam you're better off going with the smaller chamber than more airflow. honestly you'd be hard pressed to notice a difference between the two. more airflow may help if you went with a big cam, but more compression helps on big or small.

def upgrade the oil pump and chain. and the LS6 intake is VERY worth it, as are the headers.

if the car runs good, a rebuild shouldn't be needed. but it IS one of those things that you can never predict. guys trash their bottom ends on cars with 30 or 40K miles sometimes. others get years out of 150K mile blocks.

Sounds like you have a good starting point on what you are looking for. Give me a shout when you get a few minutes and we'll run over your combo and what you are looking for out of the car. We can get you setup with a package to get you where you want to be without breaking the bank but getting the most for your money.

TSP has good deals, and have proven to make power. Those 224 and 228 cams have been proven time after time to make great street cams. Now for driveability....that is in the tune. My cam is a 242/248 111 lsa, and I have no issues driving it anywhere. Week after the install, I drove 8 hours to Albuquerque NM. I drive this thing from Phoenix to Sierra Vista (3.5 or so hours) on a regular basis, and even in rush hour Phoenix traffic. If you have a good tuner, then most cams, even on the large side like mine, will be fine for driving.

I also saw these heads and did not at all think it was a bad deal . I see most LS6 heads go for almost 500 bucks and then most any port works is at least a few hundred and these PRC Stage 1.0 LS6 CNC Ported Heads at texas speed are less than $1100. It states that they gain 50rwhp. If that is true that is a great deal.

There stage 1 LS6 head seems to work good even in my 402. I'm sure I would net more HP with a better flowing head and some more cam in her but those heads flow plenty for a 346 IMO. You cant go wrong with a 228r and the stage 1 LS6 or 2.5 5.3 heads.

You make some good power with a "small" cam for a stroker and those heads! Some $$$ heads like AFR 225's and a custom 24x/24x cam could do work with that thing. But that set up seems to work damn well man.

I think my setup works well mainly because my DCR being just under needing race fuel and I was told my quench was perfect. I had my setup up ran though a engine program that my dads professional builder uses. He told me that this cam would be perfect for the heads. I had them flowed and the cam he spec'ed was damn near the same as the MS3 so I went for it over a custom cam. I would love to get some TFS 225's or TSP's 215 heads and put in a 248/252 .62x .62x 113 LSA size cam. Too bad I cant afford either of those heads right now

Yea, for the 408, I was thinking a 252/258 with .64x/.64x or something similar. I am not a cam guru though, so I would have Ed Curtis spec me something. Nice heads of course..but when I do my budget build 408, I'll just use this cam, port and mill the 243's, have reliefs in the pistons, and have at it.

I run the 2.5 heads and 233/239 cam and driveability is great. I mostly drive it on weekends but have taken car to work and sat in that horrible Houston traffic. No issues at all. Car pulls SO hard up top its a blast to drive. I made 431rwhp through an M6.

Fifedogg

iTrader: (15)

IMO you would be going too big of a cam for the 243's on a 408. Even with a 225 TFS Head I wouldnt go quite that big unless it was an all out race car. But as you stated above you nor I are cam guru's I'm just sharing my opinion

LUISP

what other mods do you have on your car? im looking into those heads as well. i got 393whp right now and if those heads can put me where your at then hell thats a deal.

headers, 92mm fast intake and true duals. Make sure you get the car tuned by a good tuner. It makes driveability a lot better.

i'm not trying to jack the thread but how aggressive of a cam do i need to make low 400s with stock heads, full exhaust, and intake?
