    Cowl Hood

    Someone fabbed this up with two 90's truck air cleaner bases. You could then run the tall lid which would give you the factory 5" air filter element.

    Where do I buy new interior kit?

    I bought the Coverlay panels a few years ago, but have yet to install them. Quality seems good to me. I'm going to remove the glued on felt inserts and use factory style ones. The inserts and sun visors were from USA-1 and took 6-7 months to receive and that was 3-4 years ago. They match...

    What is this relay looking module box on my valve cover??

    Yep that's it. I know for sure it ties into the emissions system, but I've never hooked up my cruise control, so I'm not sure if controls any part of that system.

    87 Stock TBI 350 air cleaner lid flip upside down? Does it help? does it hurt? good or bad idea?

    LMC Truck carries the small block version for carbureted trucks. 38-4359 is the part number. I have the GM part number for 454 trucks on my home computer. I had already bought this one prior to knowing that part number. I modified the SBC version with a 4” silicone tube to make it work.

    Need quick reliable answer please- ‘83 K20 front axle question

    Been there done that. Make sure to use a master cylinder from a '78 3/4 ton. IT will bolt to the stock power brake booster. You'll need to swap the brake line front to back on the master cylinder as the reservoirs change location. My '77 K5

    1978 jimmy bolt on roll pan

    Take a look under there. The frame horns are the attachment point for the rear bumper, at least on a 77. I don't know if they changed the design for '81 and up like they did for the front bumpers. My only reference was for a 4wd frame. I sold that truck 20 years ago.

    1978 jimmy bolt on roll pan

    Are you cutting the rear frame? The problem with a K5 frame is it extends past the body to the rear bumper. The springs that help lift the tail gate are hidden in there. I had to extend my custom bumper on my K5 back in the day due to this. OEM filler panel

    81'-86' Air Cleaners

    I’m pretty sure it did. I think the main difference, at least with 454s is California had an EGR where the Federal trucks did not. I know my ‘77 K5 had HD emissions with an SBC 400 , smog pump and charcoal canister. I can’t remember if it had an EGR. It ran on Regular. @VPC20HD here's my...

    14 bolt question

    2WD 454/TH400 Suburbans got the full float 14 bolts. I had an '88 and my friend had an 87. 4WD got the 14 bolt SF. Also if you bypass the valve on the rear axle your rear brakes will work 100% better. That's a weight sensing proportioning valve. GM has had problems with them. I've removed...

    81'-86' Air Cleaners

    My 85 K30 (454) came with the taller air cleaner lid. I added it to my '79 K15 (350). It's 2" taller (5" air filter). The bases are the same. I took that air diffuser out of both bases without issue. I believe the metal ring attached to the base is actually for flame retarding in case of a...

    If you have the same brackets as mine in the above post, here's how the rest go.

    Dumbo mirrors

    On factory mirrors there are two bolts that clamp the mirror head (#8) in the diagram. I put on LMC mirrors on my truck and it uses Phillips head screws. Mine keep moving, so I’m going to put the LMC mirror heads back on my factory bases and hopefully that will stop.

    Dumbo mirrors

    I found this picture of the OEM instructions , unfortunately they were already cropped. I found another thread on here where I described the location. The center of the mount is about 1/2 way between the vertical post and the wing window handle. The door has a flat area to mount the mirror...

    radiator mounting questions

    I believe the remote bracket is the same from ‘80-85 mid year. I recall my 1980 454 being the same. The bracket changed 1/1/85 through the 1986 model due to the dual smog pumps. I have see people mount the reservoir on the core support. I believe 67-72 was done that was. Only other source...

    454 exhaust recommendations

    I have factory manifolds and all the emissions equipment in this video. Sorry its a short video. I have 2.5" pipe with Flowmaster Super 50's. Also an H pipe in there.

    A whole forum just for GM Squares?

    Thanks for the kind words. I've owned a lot of 2500 Suburbans too (lol). 88, 93, 94, 95, 01 & 04. This was my favorite. A '93 C2500 (454) I factory ordered with barn doors. If only it had the 8.1L...

    Mid-late 90s Bench

    Her's a link to a company that makes those seats. Not cheap though. I noticed in all their pictures now it only shows leather seats. They used to show a lot of cloth back in the day. https://www.qualitex.com/truck-seats/bench-seats.html

    I had to do the same thing on my K30. It's been fine for the past 4-5 years.

    Rear disc conversion with hydroboost system

    @Frankenchevy has a rear disc set up on his truck. Maybe he can provide some input.

    Bench seat latch

    My '79 had a latching seat, unfortunately I don't have any pictures. The seat rested on a bolt that looked very similar to a seatbelt bolt (below). The seat rested on the smooth part of the shank. I don't know if originally there was piece plastic, like a door striker, that covered the shaft...

    USA1 Industries

    FYI Coverlay makes door panels that are similar to the OEM ones, see photo 1. They come complete as you see them. I bought them for my '85. The door inserts on the Coverlay ones are glued on and I plan on removing them. The OEM inserts and trim will fit these panels. You can see the...

    454 w/ NV4500

    This is right from the GM specs for an '85. I'm sure yours are the same. C30 gross trailer weight with a 454 and a 5th wheel kingpin type hitch is listed below. The specs I have are for an automatic (TH-400) and it doesn't say anything about dual rear wheels or Camper Specials. Either I...

    Weird intake vacuum looking thingy maybe

    I have several different types of those on my '85 K30. Here's the vacuum map for my truck. It's a mess, but it all works.
