I have a 2001 Trans Am WS6 A4. Right now i made 352rwhp and 355torq with my mods: compcam 212/218, SLP cold air intake(without the MAF), ported TB and Flowtech LT. I was looking to go higher, but i want to habe a DD car. I was looking at the Trick Flow combos, i like the 500hp or the 485 becuase of the smaller cams. Will these combos be a good choice for a daily driving car?? I like silent cars. I have read people telling that i will need a rear end of 12 bolts and a torq converter. I really dont like the torq convertes because the kill the drivability of the car.

 

Get a custom ground cam to match the heads you choose. You can retain driveablity better this way. Patrick G will give you specs for a custom cam for a very small fee I believe (like $20 or something, not sure)
