Head & Cam question to incr. low-end torque......
 

To increase low-end torque, my tuner is suggesting stage-2 heads and mild cams for my 02 GT. It has a Paxton 1000 S/C, Longtube headers & H pipe, and Magnaflow catbacks. Just installed 3.73 rearend. The car is for weekend pleasure "cruising" only...it's never taken to a track. I love the "cammed" sound ...but will this help the low-end punch? Should I leave the PI heads and replace just the cams? Suggestions appreciated.

Well, cant really speak for other companies grinds, I know the Comp Cams Mod Family pretty well though.

I'm going to be Supercharging mine hopefully here in a 2-3 months with a Paxton Novi 2000. After I recover from the cost of the suspension parts, and axle (Yeah, my rear-end up and died) rebuild.

If you put the mild Comp Cams, or cams from other manufactures with similar specs..your going to get a pretty smooth idle, like stock. Sure you'll increase your low end, but your not taking advantage of Stage Two heads with cams on the lower end of the spectrum concerning Specs.

Get you a set of Comp Cams 270, or Mod Max's 267's (If I remeber thats there duration adv.) you'll get a rumpty idle. I was surprised by how my car sounded with the 270 Cams. Its pretty rumpity...and drop the 3:73's, get 4:10s, and the stage two heads..With a blower..you'll be on your way to 600 Plus Flywheel Horse Power (Thats what I'm wanting to see when I put a blower on mine)

You'll loose some bottom end though...warn you a head of time...cant really have a cam that makes its power down low but has a beefy sounding idle. I would explain but that would be like a books worth of typing, and I'm at work now.

If all you want is more bottom end..dont do cams, keep your stock ones and just get the heads.

THough If your not going to race it at all, why bother? Doesnt make sense, thats alot of cash to only go cruising with.
