im doing alot of mods to my 01 gt bolt ons and some ported heads and cams... later on i will be adding a supercharger hopefully around income tax time but i want to put some cams in but im still doing my homework on them.. straight to the point i want to be supercharger ready and still get good gains with out the sc just in case worse comes to worse and i dont add a sc. i was lookin into comp cams xe270ah 234/238...
i appreciate all of your advice and knowledge, thanks
You need a cam with extra exhaust duration and a wide lobe separation for a FI application. You'll find that most will advise against a cam when adding a blower.
I'd wait to do the whole deal at once, given your unique situation.
Bank your money and wait.
When you are ready to do the SC AND the heads, discuss the situation first off with the SuperCharger supplier. See what they recommend for your car. Come up with a horsepower goal you are shooting for - a SOLID number - and have that in mind when you start buying parts.
You may find that mild 262's (Comp Cams) will do just fine. A lot depends on WHICH blower you choose.
If you NEED to install new cams (depends on the current condition of your motor, of course), make your SC choice now and get their input before you make the jump to a cam that is a poor match.

yeah, i need to install the cams because my heads are warped so if im goning to change the heads to get it running again, might as well change the cams as well while we're in there...SC going to come later due to my budget.

OK, then the choice you need to make is which kind of Supercharger - centrifugal (ProCharger, etc.) or twin screw (KenneBell, etc.).
Then contact that manufacturer (check out their websites - both of the ones I mention have extensive recommendations for their products on line) for cam info.

Listen to tripleblack. I couldn't have given better advice. I would recommend talking to local tuners and comp cams as well. Comp cams techs are really really smart.

Comp Cams has a lot of data on their site, but nothing replaces a real conversation. I like Comp Cams a lot.
This thread has done what needs to happen - gotten the point across that cars are a LOT more than just motors on wheels.
It also SAVES you a ton of money to upgrade either simultaneously - or even backwards - through the drivetrain. Having a strong tranny sitting there behind your so-so motor will just make the car safer and more dependable - and cost you nothing in broken parts. Having that shiney new hot motor sitting in front of you tired old drivetrain, though, will do the opposite...
Hey, let us know how it does - just go easy on the launches until you get the rest of the drivetrain up to snuff, OK?

Well, I would not put a cam designed for N/A applications on a car that will eventually have FI.
There are many different cams designed for FI applications. There are some designed specifically for nitrous, centrifugal blowers, roots blowers, and combinations of the like.
Obviously, the more exotic the cam, the more the thing will cost.
Cams are not the biggest bang for the buck.
Like exhausts, people look to cams for claimed power increases and, of course, the incredible sound.
Unless you get a cam specifically designed for your EXACT application, you will not achieve the numbers you desire.
In fact, if you buy an off-the-shelf model, you might actually lose power and increase wear on your valves.
Also, be sure to remember that most cams open and close valves faster than stock cams by having a sharper lobe profile. This means that the impulses on the valves are much higher, which translates to shorter valve lifetime.
Therefore, you should not only change your cams, but also replace your valves, springs (I recommend beehives), and seats, etc...
Hmm. Sounds like we're getting into it pretty far.
At this point, the product prices get insane, not to mention installation fees if you can't do it yourself.
So, you're spending around 2000$ for parts and installation if you're lucky. All for an astounding 30-50hp. Wow.
Or, you might as well go the extra mile and buy new ported heads with the cams installed. There, you might get about 70hp at the most. THEN it would be somewhat worth it.
There are many other things that will get you more power for the dollar. Like Methanol Injection or an intercooler system.
My gawd, dawrr, this looks like one of my brain dumps!
LOL, you're right though. Like I told him (somewhere in one my own long list posts), he needs to decide where he wants to end up before he starts buying cams.
Its always the same story. All the children (parts) need to play well with the other children (parts).
Throwing random parts at a car is not the way to win the game.
Hope Sammy is well - he is still my hero. I had his video on my favorites list for a long time!
