Default heads or supercharger????

hey im running a gt-40 crate block, with gt 40p heads,FMS cobra intake, 70 mm throttle body, 76mm c&l maf, 24 pound injectors, 190 fuel pump, adj fuel pressure regulator, tremec 5-speed, mac headers, off road h-pipe and flows, msd 6al, blaster coil, electic fan, under drive pulleys. 3.55 in the rear end. Would it be better to go with new trick flow track heat heads or a supercharger at this point? Also any estimates on what im running for horsepower at the moment?

i would keep those heads on there, they are already pretty nice. but if you sold them for trickflow heads, you would get a decent return for them.

it would be wise to do the heads first if you plan on supercharging later.

my guess is 300-305 hp?

There's a huge difference in performance between these two and also in price. For what you have and if you have the cash, I'd say go with the supercharger. You definately won't be disappointed. Then again if you go with heads, the performance gain may not be enough over what you have and you'll end up getting the supercharger anyway. There is no way to tell how much HP you are pitting out now, but I'd guess with that combo you'd be somewhere in the 275 range.

Think of it this way, you'll want to change the injectors and maybe the fuel pump along with adding the blower.

both will be good, if you have the money for the charger go for it. But if you want to do it right, I say get the heads, matching intake, then super charge it later. You will be happy either way, but I think if you went supercharger first, you are going to constantly hear, "could you imagine what your car would do if you had better flowing heads and intake?"

Your're going to make more power with the supercharger. Your heads aren't bad as is. With a good supercharger and good tune, 400+rwhp is attainable with your combo. New heads will not put you anywhere near that mark. As far as power goes, I'm guessing in the 270rwhp range (tuned of course).

yep, the supercharger will put over 100 more wheel horsepower than just adding heads. mmmm forced induction.

yes super charge it , your pressurizing the intake , i know flow is important dont get me wrong but the sc will do fine , the heads arnt that bad , just as long as you can get it out (good exhaust), have fun with it and get the heads intake later , imo

supercharger all the way, you already have decent heads, and some SC come with all you need included, i know vortechs are made to run on stock cars, so you migh not necesarily need to get new injectors and all the other supporting parts, (all depends on what you want to accomplish) call around, talk to some shops, see what they recommend. steeda has kits give'em a call see what they recommend.
