    I have a 94 S10 4x4 with a 4.3 vin W that took a dump. I have a 5.7 out of a 97 C1500 Silverado to put in with all the wires and ECM except OBD2 port. I'm trying to figure out if I'll need all the wiring or if anything already in the truck will work or any problems I may run into. I've...
  2. S10 / Sonoma
    Hi, wonderful forum this place is so active! I have discovered an oil leak on the rear of my engine and I’m not sure what to make of it. It seems like the pan is warped maybe from the block? I would greatly appreciate some assistance as I don’t want to drop this pan if I don’t have to. I would...

    So a while ago i straight piped my s10, i have the 4.3l and i love the sound, although my neighbors hate it. When i did this i just snipped the o2 sensor and figured it wouldnt matter, but im not sure anymore. I did the exhaust about 2 months ago, recently after a car meet, where i revved the...

    Hi guys, I've posted in a few different spots in this forum, but I figured I should start my own thread with my build progress & to document everything. So, here we go. I acquired a free 1988 S15 from my neighbor who had it stored on his property after it died on him driving on the freeway...

    Sorry if this has been posted before, but all of the other threads I found were non-conclusive. Little bit of a backstory on the truck. I got a 1988 S15 with a 2.5l iron duke from my neighbor for free since it wasn't running. Ended up having a hole in piston #1, I decided to swap out the engine...

    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...

    4.3 vortec parts

    What is a fair price for bulk? Block has seized crankshaft but everything else is good.

    Howdy howdy. I’ve heard that swapping a 5.7 vortec into my 96 4.3 is a really easy swap (well as easy as swapping an engine gets) does anybody know what is the biggest cam I can throw into an l31 without needing a tune? I heard I can put an lt1 cam and get like 10-20 horsepower and around 20...

    Howdy fellas, from what Ive heard the later 4.3's ( made 195-200 hp) and my 4.3 vortec makes around 170-180hp, what was the difference between them? From what ive heard the cam was different so if i can go to the junkyard and steal 20 horses that's a win in my books
