Mr Gasket makes some thin ones. Just make sure your lugs are long enough.- Craig 85

Which dually - 8.1 vs pre-DEF 6.6?
One thing to remember in all this @Frankenchevy lives in California and whether it’s gas or diesel he probably won’t be able to tune it. I left CA 3.5 years ago and emissions have only gotten worse since leaving. My understanding is if you do have a tune, it has to be a CARB approved tune...- Craig 85

Which dually - 8.1 vs pre-DEF 6.6?
I've had three 8.1's. Loved them all. The one thing I will say is make sure it has 4.10 gears (GT5). My favorite of the 3 was this '01 2500HD. I had 285 tires, true dual exhaust, a K&N cold air kit and a Hypertech chip (that's all they had back in '03). It ran great. I could pass people on...- Craig 85

Tire/wheel recommendations
Sorry late in the game here. The grey/silver truck was my '79 K15 that came with an old/stiff Rancho 4" lift. Back then it was wearing 15x10" wheels with 33x12.50x15's. The front fenders were trimmed when I purchased the truck. I went to a 4" Tuff County EZ Ride lift when I did the 3/4 ton...- Craig 85

2000s hydroboost into a square
Since someone posted on this old thread I’ll add some more info I’ve learned. Not sure if it will work on a Square Body though. The original post was asking about putting on a GMT 800 series hydroboost. I’m part of a couple Suburban 2500 groups. Quite a few guys have switched over to a 2011...- Craig 85

Need H6 AC compressor brackets for 454
The brackets I purchased are designed for a Sanden (508 in my case) compressor. Although the HR6 is similar in size I don’t think the it would work with my brackets. -

Tire Size for K10 Heavy Half
Those wheels look like a 16" wheel, not the standard 15" that would be on it from the factory. If that's the case you could probably run a 285/75R16. Those are only 32.8" tall and about 10.5" wide. If you have an 8" wide wheel or less it shouldn't rub.- Craig 85

Hello From NorCal
You have a California HD emissions truck, so no cats. Just make sure all the vacuum lines are connected correctly and all the parts on the air cleaner sticker are in place or you will fail. Check the timing too. FYI look at your fill pipes. They are probably larger diameter than the standard...- Craig 85

What is this side duct for?
The snorkel tube attaches to it. I had to use this silicone tube as an extension as the they don't reproduce the BBC version. I also cut the cap off mine so it works more as a ram air. I don't forge water, so I'm not worried about water.- Craig 85

K20 Wheel/Tire Confirmation
I’m old so I don’t deal with offsets. I know my current truck and several prior ones had 4.5” of back space on my 16” & 16.5” wheels. They had no issues with rubbing even with a 15/36 radial. Current K30 has a 16x10 wheel with 4.5” BS and a 305/70R16 (32.8”) tire. Your 285’s are also 32.8” tall.- Craig 85

HVAC Vacuum setup
HVAC and cruise control use the same vacuum canister that originates on the driver’s side. Here’s a diagram. Disregard the area on the left side in the box, it doesn’t apply to your truck. -

My ‘85 Silverado only has one vacuum pod on the driver’s side. Early trucks have the passenger side pod. -
Vintage Air Gen V (5) or replace existing compressor, etc., for 1987 R20 Suburban?
Here’s the page that lists my parts. https://www.gmsquarebody.com/threads/1985-k30-resurrection.18494/page-13 I did use the fan temp sensor for a 350 as I couldn’t find a 454 version at the time. I haven’t had a GMT 400 in 20 years, so I can’t tell you what would interchange other than the... -
Vintage Air Gen V (5) or replace existing compressor, etc., for 1987 R20 Suburban?
@beady when I added my fan I found out the ‘85 OEM style sensor was discontinued. I used one for a GMT -400. Look around page 13-15 of my build. I listed all the parts and numbers there. -
Vintage Air Gen V (5) or replace existing compressor, etc., for 1987 R20 Suburban?
I lived in Nor Cal for a couple years after I installed the A/C (95* occasionally) and now in Mid TN with heat and humidity. A/C temps were in the 40s. I only have Boom Mat in the cab right now, still need to add jute and carpet. I only drive my truck 500-1000 miles a year and where I drive it... -
Vintage Air Gen V (5) or replace existing compressor, etc., for 1987 R20 Suburban?
I actually added it. All my other 454 trucks had it. This truck didn’t have the Z82 tow package which included the aux fan. It was easy to add. The fan is controlled by a temp sensor on the passenger head (OEM setup and parts). It’s basically a ground for the fan relay. It turns on/off at... -
Vintage Air Gen V (5) or replace existing compressor, etc., for 1987 R20 Suburban?
I had an aftermarket in dash A/C installed years ago on my '80 crew cab. Vents were in the OEM dash locations and used the factory heater. It could not keep up with the larger cab. I lived in Nor Cal at the time. Last year I helped a friend install a Vintage Air in his '62 Bel Air wagon... -
