    Thanks. Does anyone know what major frame differences exist between a C and a K frame?

    4x4 Conversion Question

    Thanks for the replies. I actually have a rusty 4x4 87 K10 that I bought for the AC setup. However, it's a short box with a floor (stick) shift. How much from a half ton, manual shift 4x4 would work on a 3/4 ton? The K10 axles are 6-bolt hubs compared to the 8-bolt hubs on my C2500. I just...

    4x4 Conversion Question

    Not sure if this is the correct forum location, but wondering on the logistics for converting a C2500 to a K2500? Subject would be a 1983 GMC. Currently has 350 with TH400 transmission and 3.73 rear end. I know that a body swap would (probably) be easier, but the frame on my truck is nearly...

    EFE valve for 350

    Looking for EFE valve in good working condition. EFE valve is the heat valve that goes between driver's side exhaust manifold and exhaust tube. Need for 350 sbc with stock exhaust manifolds. Would like any metal vacuum piping if that is used in the setup. Thanks. Looks like this:

    Rear Differential Questions

    I'm pretty sure that the rear differential that's currently in my 83 GMC C2500 is a 14-bolt, 9.5 inch semi-floating, but let me know if the pictures show otherwise. I'm wondering what I can do for a limited slip function. Can I just swap out the internals of this rear end for a limited slip...

    Correct Choke Relay Location

    Thanks for the info. The engine is a replacement (1975 vintage if I'm reading the engine codes correctly) and it only has the oil pressure sender and no extra hole for the pressure switch. If I want to go back to the original method I've seen the suggestion to just put a Tee fitting in between...

    Which Quadrajet Carb Question

    Since I first posted I picked up a GM 346249 intake to use. It's cast iron but should work OK with the Q-jet. Got it cheap so if I switch to something else I'm not out much.

    Correct Choke Relay Location

    Not sure if this is the right forum to use, but have a choke question. My 83 GMC C2500 with engine code 350M currently has a rigged up electric choke setup. What type of choke would have been original, would it have used a choke stove in the intake manifold? Engine is a replacement with...

    1983 Emissions Hose Routing

    One of the items that is partially torn might be the "DVTR VALVE"? What would that be?

    1983 Emissions Hose Routing

    Back again with another question that hopefully isn't beating a dead horse. This is what's remaining of the emissions diagram from my 83 GMC that had/has a 350M engine. What's missing from the portion that is torn off on the bottom right?

    Simple Valve Cover Question

    The 350 V8 in my 83 GMC has valve covers that each have two flat brackets with a couple of holes. Are these for mounting spark plug wire holders or serve some other function? Thanks.

    Which Quadrajet Carb Question

    From what I can tell the intake on the engine right now is an Edelbrock Streetmaster, for what it's worth. I've included an internet photo. It's 1998 vintage or earlier, as I got the truck early in 99. I'm guessing I'd get better performance if I either went to a spread bore intake (not...

    Which Quadrajet Carb Question

    There was a lot going on when I got the truck 20+ years ago. The PO was someone trying to rod up the truck, which is how it ended up with the Edelbrock and the headers. There was a bunch of stuff wrong with the engine swap that had been done as well. I've put up with it since then as the truck...

    Which Quadrajet Carb Question

    Thanks for the replies. Not sure on the Edelbrock intake. Where does Edelbrock put casting/ID numbers? I'm going to try and clean 40 years of gunk off the engine this weekend so might be able to find any identifying marks if I know where to look.

    Which Quadrajet Carb Question

    Hello all, I posted this over on Cliff Ruggles' Quadrajet site but will put the question here as well. I'm trying to figure out the best Quadrajet to use on the engine in my 83 GMC C2500 (3/4 ton). Here are the specifics: 350 engine (not original, CMJ suffix and engine VIN denote possible...

    Off the Shelf Exhaust Question

    Do I have to be concerned about which stock manifolds I'm using and how they fit with these systems? The manifolds that I have are LH 14079295 and RH 14034069 (with the heat shield/stovepipe).

    Off the Shelf Exhaust Question

    Anybody have part numbers for a dual exhaust system used (or would fit) on a 1983 C2500 pickup with 350M engine code? No catalytic converters, AIR or other emissions items. I'm reverting back from a cobbled up header job with dual exhaust but would like to keep duals. When entering in the...

    Removing PS Pump Pulley

    Has anyone used the pulling kit from Harbor Freight for removing the pulley from a power steering pump? Thanks.

    Power Steering with AC Bracket Question

    Not sure of what forum this belongs in, so will start here. I'm going to add stock air conditioning to my 83 GMC with a 350, using the A6 compressor. Tonight when I pulled the brackets and compressor off a donor 1970s wagon at the local salvage yard, the power steering pump had a different...

    Carb to TBI Conversion

    I acquired an 87 1/2 ton parts truck for doing an AC conversion on my 83 3/4 ton GMC, and am now wondering about the TBI setup in the parts truck. Are TBI setups in demand enough that it's worth trying to salvage and sell? Is it worth converting the 4BBL carb setup in the 83 to TBI? As there...

    In-Bed Spare Tire Mount

    Does anyone make an aftermarket in-bed spare tire mount for 73-87 trucks? Or, has someone crafted one of their own and could share a picture? I keep the spare in the bed of my 83 GMC and am tired of it always being in the way...would like to mount it to bed but hard to find original in-bed mount...

    AC Compressor Brackets

    Thanks, so what I'm looking at is the bracket for the compressor rear. Now to figure out what the front compressor looks like. I forgot to mention in original post that this relates to 350 sb.

    AC Compressor Brackets

    I acquired a parts truck for adding A/C to my C2500. However, I'm wondering if I'm missing some of the compressor mounting brackets. Here's a photo of what is currently on the parts truck, which is an 87 Chevy K10. What's missing for compressor mounting?
