About an hour and a half. School starts the 21st of august and I will be in fort Scott (about 30 minutes north of Pitt.) If he doesn't get it welded soon enough I'll look into it! I think I'm going to cut the 3/8" line and then drill it to 1/2" and run some stainless 1/2" in its place.

Re: 1971 k20 badmax

I've been busy lately with moving down to college and such. I managed to sell my 3/4 ton axles, so now it's time to rebuild the Dana 60 front. Now I can have 4wd too. Intercooler pipes are welded but I failed to take a picture.

Re: 1971 k20 badmax

Well my truck missed the goal of the carshow. But I took the C20, and still had a good time. 2,123 cars were registered in the show, there were some pretty cool cars and trucks there. Anyways, my axle rebuild is slowly coming along since I am only able to work on it on weekends. My Fass lift pump is mounted and he's doing some plumbing for the fuel. A/C is in the works too.

Re: 1971 k20 badmax

I'd say A/C is a must before you start driving it. Other wise you'll be driving it with no AC like me.

Re: 1971 k20 badmax

Haha. Yeah, I'd probably almost always drive the Camaro since it has pretty good A/C that I'm hooked on now.

Re: 1971 k20 badmax

The Dana 60 front has been blown apart and cleaned. We are now painting parts of it and itís about ready to go back together. The AC has been hung in the dash and the holes have been cut!

Re: 1971 k20 badmax

Nice to see a duramax k20 build here! Ive got a couple questions if you don't mind. First was the duramax rear axle wider than the d44 that was in the front? And how little lift could you run with a duramax oil pan? I have a duramax parts truck id love to use to power my 70 k20

I don't believe it was wider, looked pretty close to the same width. I never measured or anything. It all depends on how you do it. If you put the engine in your 70 frame, you will have to build your own motor mounts and possibly a crossmember. Also to keep it a 4x4 you will HAVE to use a 78-79 ford dana 44 or 60 (60 Recommended) to clear that offset oil pan. My crossmember as you can see is over kill. It can probably be done with 3-4 inches of lift, but there are a lot of factors that can change that. The pumpkin is large, so, how high you set the engine in the frame, how large of a crossmember is used will all determine. You will also probably have to trim the frame rails for the manifolds. The manifolds sit really low on a duramax. Or you could possibly body swap it? Hope that helps

Re: 1971 k20 badmax

Yeah it's always a cascade effect when you change anything major like that.I'm guessing you positioned it so the manifolds were an inch or so above the frame rails and moved it forward enough for the heads and turbo to clear the firewall?
Also no body lift right?

Manifolds arenít all the way above the rail, not possible without a body lift or maybe a cowl hood. There is some clearance in the firewall, but not a lot. No body lift, I hate body lifts.
