ejf,
Last summer I added an LT4 HotCam kit to my '96 A4 coupe. My plan was to add the new cam and then add a new TC next year. I have to say that the drivability of the car was greatly affected by adding the cam and having the factory TC. I had the ECM retuned but the factory TC would just not slip enough at stoplights and such without the car lurching very badly. it almost seemed like a safety issue. I had to put my foot thru the brake pedal to keep it under control. If my foot ever slipped off the pedal, I was going to nail the guy in front of me! I've certainly read many people saying that they could live with the factory TC very well but I could not.
I added a Yank 3000 TC and that made the car fun to drive again (at least in town traffic). Maybe you won't have the same experience that I had but be aware that it might be the case. Good luck with your mods.
Regards,
RayJay :)

Re: LT1 Cam question (ejfagala)
THE SPECS FOR THE HOT CAM SHOULD BE 218/228 DURATION @50 AND 525 LIFT BUT WITH 1.6 ROCKERS. IF YOU TAKE THOSE AND COMPARE THE NUMBERS ALMOST MATCH. DONT FORGET THE CAM SPECS YOU LISTED ARE WITH 1.5 ROCKERS.

and the specs on Comp Cam 502 are 050 218/224 @ .050 495/503 lift with 1.5 rockers
I am just woried about the duration with a stock converter I think I am going to go with the 845 Cam 214/224 488/509 with 112 LS using 1.5 rockers it has a little les duration than the Hot cam and I think it will be a little more driveable on a day to day basis any feed back is welcome
