  2. Transmission & Rearend
    So first a brief description of the state of things then the questions: I have a 2003 s10 4.3 4x4. It rides on 5.13 ratio axles and 37" tires. A while back I sent my ECU in for a wait4me tune and after getting it back, it read the speedometer dead on. Recently, I had to pull transmission, tcase...

    Just picked up this 1998 S10 for $500. Needs some work for safety and cosmetics, but it runs like a champ!

    Alright here goes: Bought the truck about three weeks ago, drove 2h45 the night of purchase - never went above 58mph, temp gauge never rose above 140F. I've driven the truck a good few times about ten miles one way and the temp never rose above 140F. Yesterday I took the truck on an hour long...

    So I want a cam that’s going to increase hp and torque that’s reliable and I don’t have to do any machining or valve train work to. Any suggestions on cam options or what specs I can get away with? I have a 2000 zr2 4.3

    2003 4.3 vortec Misfire issues Not bad at idle worse around 1000-1200rpm then smooths out some from there up. I just want to know where to start with fixing it.

    I have a 2001 s10 4.3 v6 around 91k miles. Engine light came on and I’ve noticed a loss of power and rough idle. Took to autozone and code reads misfire cyl 1. I started with replacing spark plugs, wires, distributor cap, rotor, air filter and fuel filter...runs a little better but still have...

    So after 350K+ miles on my 93 S-10 the old 4.3 bent a valve and is running like crap. I have a 99 blazer that was rolled a few years back that I planned on pulling the 4.3 out to slap into the pickup. I already have a new Edelbrock 2114 intake manifold and a TBI adapter plate. Also I am building...

  11. S10 / Sonoma
    I've got a 1999 s10 2wd(4.3/auto) and from my understanding I have 3.42 gears In the rear end. I like to do a lil racing but it's also my daily and I wanna lil more oomph (tired of getting my tail whipped by a 3.0 ranger?) I spin through second and was looking at getting 3.73s with posi Trac in...

    If 2wd hasn't scared you off already, hope you stick around. I'm buying the first truck I owned back out from under my dad to run in the Nebraska Gambler 500 this year. Its a 1990 S10 Tahoe, extended cab with the 4.3, 150,000 miles, but the body is rotting off around it. Frame is mint, but the...
