Aside form the V6 itself....I think most of the issue with the 4.3 fullsize lies in the fact that it's coupled with a 4l60 and shitty shift programming/torque management. A gear swap would probably help more than a cam swap as most came with the 3:31? gears. I know my 06 has the factory pedestal mount roller rockers, EGRless intake and upgraded MPFI injectors.
Where'd you come up with 3.31 gearing? Are you meaning 3.23 or 3.42?

I meant 3:23's

I'm getting my GM truck/ 8.8 ford ratios mixed up; hence the ? mark

3.73's would be a nice upgrade. I actually did that before the cam.

4.10's if you have 29" or shorter tires. 4.30's if you have 30" or taller tires...

Default 4.3 v6

Go ahead and have some fun with your V6. I have an 2000 S-10 extreme
with a 4.3 w/4l60 3:73 rears,tuned and a few bolt ons. It runs 14.80s at 90+
I beat a lot of V8 full size trucks. they can't believe they got there ***
wiped by a V6. :nunchuk1::nunchuk1:

You're also in a little bitty wimpy s10. Add more weight and more wind resistance and see how much you like that V6...
