Yet another GMC build

[OKGMC4]

What I've been working on for the last couple weeks. Fiberglass is easy but time consuming. I just didn't want to package a cone filter in the corner, I can use that space for other things. But we do have tons of hood clearance and I'm still considering making a fiberglass scoop assembly to attach to the hood that would direct air from the GMC hood hole to the air cleaner. My two favorite cars are the 69 Judge ram air and the 98-02 ram air Trans Ams so it makes sense, but would mean a ton more work for me.

Nice Build!!!

What air intake is that???

The airbox and mounting bracket I made with fiberglass and 1/2" square tubing. The two rubber elbows came from PepBoys. The air filter is the K&N I took out of my Ram. I have Dodge seats, a Dodge fuel door, and a Dodge air filter...maybe I should paint it Plum Crazy purple!

for the Plum Crazy Purple....What are the dimensions of that box???? And how did you make your mold???

Wood, cardboard???? It looks really cool.....and different. I also like JML55's intake setup. Options, options.....options.

I used a cardboard box. I forget the dimensions and I'm at work right now but it had to be tall enough to accept the MAF sensor. It's 3.5" on the inlet side so any 4" box would work. The other two dimensions are only limited by the air filter you choose. I would have used a smaller box if the filter had been smaller. I'd say going any bigger than an 06 Hemi Ram filter would be overkill. It's pretty big. I wrapped the box in saran wrap and glassed it a couple times on each side. I pulled the box out when I cut the filter hole. With a 2 hour set up time between flipping it over with 2 layers on each side you can do the math and see it is time consuming. For the lid I used a piece of 1/2" plywood. I had to use a router on the bottom side to make it sit over the filter and the depth of the cut is critical for sealing. The lid actually needs to compress the rubber seal about 1/8". I soaked the wood with a coat of fiberglass resin to seal it and both parts got a skim coat of bondo to smooth them out. For the countersunk bolts to attach I tried a couple different things and the only one that worked was to weld a 1/4-20 nut to a fender washer and gorilla glue it on the inside of the box. Hope that helps some.
