hit a wall

i have a 4.0 sohc v6 and im at the point where i dont know what else i can do to make it faster. i have the cat back, the intake and the chip, and i tweaked the voltage on the throttle body for better response. what else can i do to make it fast? has anyone added after market pullies? is there a after market throttle body for the SHOC at all?

follow Aldives lead. he has made huge HP gains with his mods
 












MAS, TB?
Electric fan is good bang for the buck.
 






Camshafts I always heard made way more power gains than any of the other stuff.

Or just go crazy and swap in a 5.0, then you get to do all those previous mods again!
 






Not sure there are custom grind cams avail for the SOHC, what a bit&^ that would be to install on that engine, mine as well pull it out.
 






i think you want to upgrade to metal pullies and timing chains (plastic timing chains? or did i make that up?) before you do anything else.

i dont know really anything bout the SOHC engines, but thats what i hear as being the weakest link with them.
 






What axle ratio are you running? Swaping to a lower ratio will not make the truck faster, but it will make it feel faster with better acceleration.
 






Creager, I think it's the guides/tensioners that are made of plastic. It's hard to make a heavy truck fast, especially when you add the hurdle of muddrs and a lift. Yoiu may want to consider an oversize tire with an all season style tread that is lighter, and has less rolling resistance.
