Hey guys so I been searching for a while for a good cam for my 2000 z/28 but can't seem to find a perfect one my mods are pacesetter longtubes, slp lid, slp cold induction package, borla exhuast, fast 102mm intake, Holley 102 TB, and 4l80e swap, with 4K stall from yank. The car is mostly a street car but I can sacrifices a little of daily driving since I have commuter car, I want a cam that' is good threw out the whole rpm range

Any room in the budget to get the heads ported?

Also, what are your power goals?

Yes I can go with ported 243 different power goal are 450-430rwhp

You want a good set of heads that wil grow with
you we have a trick flow heads and custom cam package that would make 450 no sweat...add in better than pace setter headers and gain more.
$2800 includes heads, dual .650 valve springs, pushrods, cam, all gaskets, cam thrust plate, gm mls head gaskets, melling hp oil pump, billet hd timing set, and head bolts, crank bolt, ls7 lifters and shipping!!
After that youll need some fuel, so a racetronix pump and hotwire kit $220 and some FAST 46lb injectors and you are all set!

That kit would be all fresh, brand new, and ready to make power esp with your fast102.

450 (or pretty damn close) is do-able with ported (or aftermarket) heads. If you absolutely want to use the 243s I would get in touch with Tony Mamo or Phil at Advanced Induction. They both have excellent porting programs and can spec you a cam that'll get you into your power goals.

If you want a pre-made cam, I'd recommend something like the FTI Hellraiser 229/236 .631.631 112+2. I know guys who've made above 450rwhp with a set of aftermarket heads and this cam. (8.5 degrees overlap, you'll have a nice lopey idle but it won't be a bear to drive down low).

Fortunately you have good supporting mods, though you'll need a few more to get to that power level.

You WILL need new injectors. I'd recommend the White Bosch 3's from the Supercharged Pontiac GTP. (Part No. 0280155811) They're 42#ers at our fuel pressure.

You'll need good lifters (Recommend Morel's. 5290 if you can swing the price to get rid of the plastic trays

I'd bump compression up as well, 11.0:1 would work to get you close without risking detonation (you can go higher, just need a good tuner)

I'd recommend aftermarket rockers, for the extra valve guide longevity (and better stability) TSP is coming out with a roller set soon I hear.

Don't forget a spring kit. BTR Platinum's should work.

A dual exhaust would allow the motor to breathe better, 450rwhp is a bit difficult with a single pipe (Custom Y with flowmaster merge would make this a bit better)

Wow, that's quite the list of parts. I was putting down 435 at the tires through my 4L60E with a Yank 3600. I had the following parts and once tuned, it drove like a dream.

Tsp 231/237 598 .595 on a 112+2
Patriot Performance Stage II heads. (just 243's P&P)
Pacesetter long tubes to Magnaflow exhaust, y-pipe to 3" tips
Stock rockers
Comp 7.4 push-rods
LS7 lifters
Fast 90 intake and throttle body


There are many ways to get to your goal, it's very achievable. Do your research so your not buying parts twice.

Fuel pump isnt a bad idea but not necessary, i dont have one and im fine. I also use stock rockers and LS7 lifters for 5 years now on a .643 lift cam. Not saying those parts are not good but others work too. Exhaust is important, use 1 7/8" headers for sure and be carfull installing the valvetrain for proper pushrod lenth etc.

That's damn right. Know how budget builds get expensive? Building it twice.

Dealing with these cars day in and day out both for sales and in our shop for installs and tuning, we are well aware of the capabilities of the stock fuel system. Esp a 15year old pump if it is the stock one. The stock wiring is one of the major issues esp being 11v at the pump. Putting the system in while you are down building the car is alot easier and alot better than finding out when you are on the dyno.
The rest of the short list i provided has worked very well for 5 of our customers in various states this year. I pointed out the only real bottleneck/place to upgrade later on.
We have made 400 and later on 410 on an 01 m6 ta with a smallish cam, pace setters, catback, lid,smooth bellow, truck maf, 36lb inj, 255 racetronix pump kit. Its not hard. Past that youll need to start spending more and sometimes you can spend just as much porting a used set of stock heads vs a new set of say trick flows. The choice is yours. If you are on a budget for now, find a set of 243s or 799s and bolt em on.
The trick flow as cast heads are a GREAT budget head, and have quite a bit of room to grow and can be recycled from one build to the other if necessary for little extra cost.
You dont have to spend spend spend, but buying the right parts the first time makes alot of diff in the outcome.
Our parts may not be better than x or y or the same, but most times we are less $$ and have the tech support etc to help in nearly any situation as well.

I think this is a very solid recommendation for what you are wanting. Other than aftermarket rockers and the higher end morels, my build is almost 100% identical to this and was able to achieve 457 rwhp on a mustang dyno. For as easy as it is to cut the trap door and change the fuel pump, i would just do it, tune it once, and be done!
