  1. I cant speak to specific numbers just for the headers, especially since I also upgraded cam, intake, carb, and exhaust at the same time as the header swap. I went one step up on the cam and went to an open intake, as well as switching to duals. The old exhaust went from the shorty headers to 2.5" pipes to a y-pipe to single 3" exhaust with a flowmaster muffler. The newer exhaust is the long tubes with dual 3" pipes and borla mufflers. It definitely feels more healthy at higher rpms than before. My seat-of-pants dyno guesstimates around a 25 hp increase for all changes.

  2. nice find. i recommend buying them uncoated, tweaking if necessary, then getting them coated locally. since mine were already coated, i persuaded the floorboards to make room for the collectors with a bfh.

     

    i've stated before that the coating from s&s isn't the best quality. love the headers, though. i'll be buying a new set soon for my other project.

  3. i've had bad experiences with jim cook racing, especially jim's wife when it came to a refund for an item i ordered that arrived broken. from my understanding talking to his wife, they were moving out of the z car business.

  4. he's correct on the offset. i have 15x8 weld rodlites with 4.5" backspacing on my 240. i was previously running 255/60-15 bfg's (almost 27" tall), but they rubbed when i hit dips in the road. these will not fit with stock suspension. i swapped my rear suspension for 280 assemblies with 240 suspension techniques lowering springs. a 240 suspension assembly with a 280 rear spring will also give you the needed clearance. otherwise, you will have to go with coilovers. the rubbing got annoying and a 245/60-15 would not have rubbed in my case, but i went with a 26x10 mickey thompson sportsman pro.
