Best of Both, this is the cam I was thinking of:

It's from PAW / SSI:
194/204 on 110LSA, .464 .490 lift

With the Clifford 4v and Langton Iron, it gave my computer:
Torq 222 at 2000
Torq 244 at 3400
Power 198 at 4500

Keeps all the low end and adds top end too, and price is right. $50.00

Do you know how much the truck weighs and what trans and rear gear and tires it has? If so I can estimate whether it will actually pull better, down lo and up high.....
