Re: thumper cams?
Don't listen to doubters. The August 2008 issue of Hot Rod magazine did a comparison on the 5 most popular cams and the Thumpr 283THR-107 scored the highest in every category excpet for Peak Power Output. They can, believe it or not, build some nice power. This cam being a roller your engine will need some modifications, but it's for the better anyway. Maybe some of the guys who actually installed the Thumpr will chime in and tell you just how much they like it. Now, some guys may say they lost power, but if they were running a cam with an RPM range of say 2500-6500, then they may very well have felt a loss in TORQUE. The Thumpr is a 1900-5600 cam so it's more toward low grunt and middle torque than it is for upper power. I think you will like it, especially if all you are want is sound. Plus, you will get some fun along with the sound. This is just my opinion of course.
