    Modern brake controller?

    I am mostly likely going to use my 85 K20 over the winter and pulling a trailer w/Skidsteer and would like to set it up with a decent brake controller. I am just looking for opinions and first had experience with them on these old trucks.

    bucket, thanks for that input as always! I have made a small side business out of buying nice squares and reselling them after a while but enjoying them in the mean time so this C25 is going to be a fun ride for a while!

    73-80 454ci spec questions.

    Hey guys, just picked up another truck! We got here a 1979 GMC C25 Sierra with factory 454/TH400. I have not had the chance to own a factory 454 yet in the squares so looking for a little info. I can find all kinds of specs on 454's from 81-86, 87-95 but the 70's truck 454's are kinda tough to...

    Factory Ram Horn Manifold?

    Hey did the "Ram-Horn" style manifolds come stock on some trucks? If so was there any rhyme or reason to which trucks got them and what years?

    GM 14-SF Casting Number Identification help.

    It has been a long time since I have posted anything but I just picked up a nice "Mutt" of a square. So a little back story, the previous owner was told by the guy he bought it from that it was originally a 6.2l but had been replaced by a sbc350 which was fine with me and actually bought it on...

    I am about done replacing my rear wheel bearings and seals on my 87 V10 and went to clean up my cross pin to reinstall it when I noticed this. What caused this? Also I'm having trouble finding a replacement one.

    87 V10 TBI 350 Questions

    So I replaced all my vac hoses tonight and I got around 17-18psi but it was surging while I was doing it. So I also checked the timing but could not find the wire to unplug to get it to 0 degrees but at normal idle it seems to be right about 3/4" to 1" to the left of the gauge. I did however...

    87 V10 TBI 350 Questions

    Hello Gents, long time no see. I have since added a 1987 V10 Silverado to my collection of squares. How I Found Her! After A Little TLC! So I am very limited on cash at the moment so all my testing and tinkering has been very budget minded. It is completely original (as far as I can...

    Help me fill in the blanks.

    Hey Gents, I am going to start accumulating parts for my 79 K20 single cab rebuild and I need some input from guys that have more knowledge than myself.
