dude, thats like comparing a carbed nissan sentra to a carbed nova ss.... Of course the truck is pure love with a motor that is all aluminum and has like 390 horses, but the 4.2 is a great, dependable motor.

@blackericdenice If you go all motor, you will have to change cams and reprogram the computer and you may have to raise the compression. The stock cams are design to flow not much over than 290hp. To flow 355, you'll need to turn 7000 rpm if you keep the stock 10 to 1 compression.

@WatchOutFourMe Do you really think a chip will give a TB 60 more HP. You don't no much about an engine. Supercharge, turbo or nitro yes. A chip no. The cams want allow that much air to go into the engine.

@bdratcliffe Haters Gonna Hate!!! Your absolutely right this truck is meant for towing not for "going fast". If you wanted to go fast go invest in a muscle car! This 4.2 inline motor smokes any other full size SUV out there today and with 295 Hp combined with the g force chip of 60 extra hp that's 355hp in a 6 cylinder car! So next time think before you speak because i would smoke your pussy ass. You probably go 10 over the speed limit and think your a bad ass.Do us a favor and shut the fuck up
