Nevada95

Please keep in mind, I am still learning a lot

I am loooking at some new heads for my 95 GT conv.
Right now my engine mods are pretty simple, I have exhaust, about to purchase new shorty unequal headers, have cobra intake manifold, 65 mm TB, and a fenderwell CAI.

Along with the new heads, my future plans are to add some 3.73 gears, and a supercharger. I will probably purchase the gears before the heads, but the heads are in the near future or may happen at the same time. This is my daily driver and will rarely if ever see the track. I just enjoy adding stuff to my car.

I am confused with all of the different heads and cams out there. I will probably try to do a new cam when I do the heads. I want a cam that will work with a future supercharger, but not so extreme that it runs poorly without the supercharger as I got some interior/exterior, and suspension work to do before the supercharger purchase. Is there anything like "tuned" sets of heads and cam that go well together? Would I be better off just sticking with the stock cam?

I am told the intake manifold I have is good to about 350 HP. That is about where I want to take my car to in the end. Do you think my TB is big enough to get me to where I want to be? Will I have problem with this manifold on any of the brands of heads out there?

I appreciate any inputs. Thank you.

From what I hear the stock cam isn't bad for boosted applications. I would look at some Twisted Wedges and put some 1.7 roller rockers on it. 3.73's might be a little steep for boost....maybe 3.55's? Check w/ the guys in the boost forum to be sure....

I'd also go with 3.55s for boost, especially since it'll rarely see the track... the Trickflow Twisted Wedge and AFR 165s would work nicely on your boosted 5.0

if you have money THE AFR 165 heads are the best on the market maybe 75 hp ,...if you dont then gt40p heads with new headers are good for the street, maybe 30 hp. the gt40p heads require new headers to clear the revised spark plug angles, talk to bbk they will set you up with good headers.

I used to recommend the P heads, but it seems the GT40's flow better above .500 lift and are less hassle to begin with (any headers work, no special plugs/wires, etc.). Since I'm running @ .535 lift, I'd go w/ the GT40's and use a Dremmel on the thermactor bumps on the exhaust side.
