basic power

I have a 91 s-10 4.3 4x4 5 speed. i plan on putting a tbi spacer in it and an underdrive pulley kit. also with an exhaust. any other little things i can do to get more power?

you don't want to have to much power in that truck.......you will start having drive trian trouble i.e:transfer case

the pulley only adds 20 hp and same with the spacer plus the exhaust. would 40-50 really tear it apart

You need to dip into reality a bit.....

under drive pulleys will add 3-5hp MAX

TB spacer will actually reduce performance and does nothing for a 4,3L so don't install it.

Exhaust might add 5hp max.

whoever told you that is throwing you the biggest line of bullshit i have ever heard, listen to blazerlt, you will only get 10 horses max out of what you are doing

Here's a good list of bolt ons (includes pullies) with average hp, cost, ease of installation etc... Very thorough list. Be sure to read the bottom foot notes...
