I love how my truck sounds but you can check out the video at the following link and see there is quite a bit missing from the bottom end. its a 4.8 in a ecsb 4x4 so its heavy. Ive watched the video a lot and dont know if I should go if the 3.42 to 4.30 would be best, a 3200+ to replace the 2800 I have or smaller cam would be most economical and get the best gains http://youtu.be/NCIzOrbRNgc
