[Desmodaeus]

Hey guys. This is my first post here. I recently got my hands on an RS which had its 305 replaced with a 350 tbi. I am looking for some tips to enhance my performance. The car is definitely fast as it is, but I still have trouble against some of the newer trans ams and mustangs. So far I have replaced the old intake system with an edelbrock air induction, put in a 160 degree thermostat, and this week I plan to pull out the AC and grab a pulley with a shorter serpentine belt. In the near future I would also like to grab a new exhaust as well, but for now I am waiting to hear some opinions first. Oh, and as a side note, whenever I jump on the gas, I get a loud "bump" from somewhere near the center front of the vehicle. Could this be the transmission? Thanks guys.
