I installed an E-303 cam in my 93 GT that has a GT-40 intake and Fox Lake TFS Twisted Wedge Stage 1 heads. I had the car dyno'ed and it had 267 HP at the rear wheels. While the cam sounds awesome at idle and the power feels good, the car bucks going down the road in fourth or fifth gear below 2500 rpm. I don't like the cam and want to replace it with one that is smoother. Can anyone recommend an emissions legal cam that will give better performance than the stock cam but not have the roughness of the E-303? I am also going to replace the GT-40 intake with a TFS street heat intake. The car is driven 99% of the time on the street commuting to work but I want it to have enough power to pull some good times at the track.
