My best advice as far as what cam to get, would be to go to your local "speed shop" or "Performance Shop" and ask the folks there. There you can show them or explain the trailer, and exactly what your expecting and want from your vehicle. More torque, more horsepower alittle combo of each etc... They may also be able to turn you on to other preformace enhancers to go hand in hand with the cam you choose. I like the big catalogue speed suppliers just like the next hotrodder, but NOTHING beats the advice and experience of someone who'll show you, talk to you and generally care about the choice you make, knowing they were instrumental in that choice. Not saying all shops are that way, but most mechanics/owners know it's your word that'll bring in either your repeat buisness and/or your friends/family/coworkers. They also know the opposite is true if they do not treat you right.
Do some research, get an idea whats out there.
Go by a speed / performance shop in your area. If you cant find one ask some mechanics at "regular" repair shops where these places are. Most cities have one. Go to your local race track and ask some of these folks also.
I hope this helps.
Just advice from experience.
Good Luck
