  5. Cam guide?

    262ci Forum (4.3)
    Hello, I’ve exhausted my options and it’s narrowed down to building the 4.3 in my truck. I have a 96 and it looks kinda scary to cam a 4.3 because of the balance shaft and summit saying the cams I looked at are for 85-86 engines, What cams work for my truck?(96 btw) I don’t really want a super...
  6. Updating Look and Height with Tires

    4wd IFS
    I would like to avoid getting a kit for lifting my 95 4WD 4DR. I was thinking of getting 14 inch rims to make a set of 30s look bigger, friend of mine had custom tires made 10 inches wide to fit an 8 inch rim for extra protection and I really like the less square look. I am totally new to tires...

    262ci Forum (4.3)
    Howdy, since I just realized a few seconds ago that gm has the ecotec 4.3 with 283HP and I'm looking for a v6 swap into my truck what are the differences between the 4.3 vortec (my whip is a 96 s10 btw) compared to the ecotec 4.3? It sounds like a very good swap instead of a v8 to me (hp is...

    Weird idea but I want to be different with my ride, I want to swap in a different v6 but I don't really have any ideas what I can do, I was thinking maybe a 3.6 from a camaro (300HP v6 sounds perfect for an s10) Anybody have any suggestions?

    Hey guys, I have a '92 Sonoma 4x4 4.3L truck, and it bounces pretty bad anytime there is a change in the road. Example - driving down the highway at 70mph, if there is a dip in the road it'll bounce two or three times after going through the dip. I've replaced the shocks on all four...

  18. 1995 4.3 S10 Not shifting, no speedometer reading, abs light is on

    S10 / Sonoma
    So I've seen multiple posts about this same problem, but they all seem to have a much simpler answer that I have already ruled out, such as the VSS or the brake fuse. But mine is more complicated, in have checked the VSS, it works, I have checked both of the connections from the VSS up to the...
