SFBD square with a Cummins and custom chassis

bolt the new compessor to the floor with some chemical ankers and put a little tackweld on each nut , if they want to steal it they have to grind the nuts of it first if you mount it a little higher (to the wall near the ceiling ) you might be able to run a waterline from the nozzle at the bottom of the tank to a small sink , makes getting the condensation out a lot simpler and less messy

Looks like I'm not gunna be able to run the stock radiator from the donor truck. The intercooler was ran with the inlet and outlet at the bottom of the core support. I'm going to be turning it upside down and running the outlets of the intercooler at the top. With it flipped like that the radiator won't fit into the outlets of the intercooler. I'd have to run the radiator upside down also lol. I'm gunna try to make the stock Chevy big block radiator work with the cummins. The radiator will bolt right back in the core support since it came out of there originally. I think the 4 core big block radiator will be enough to keep the diesel cool. The only thing I'm unsure of right now is how I'm going to make the hoses work. I haven't measured yet but it looks like the outlet on the cummins water pump is about a full inch or more bigger than the Chevy radiator. Hopefully I can make it work some how.

Just chimed into the thread and i must say you have one extremely nice ride your building there sir....keep the great work up!

you can have a radiator shop put another in and outlet on the radiator , its simply a matter of entlaging the hole and braze the new ends on there , they can allso relocate them if needed
i shouldnt cost that mush to do
wat are youre going to do for intercooling ?
i been working on a twin turbo truck in my head and i figured on using and air to water intercooler myself

you might be able to hide it in between the inner and outer fender with the radiator under the seathump below the cab

Thanks a lot man!! Glad your joining us here at DS.

On the intercooler I've got the stock 1995 dodge air to air unit. That thing is huge and the biggest intercooler I can fit. I've had to cut a lot of core support to make it fit inside the core support. I really didn't know how much turbo the stock intercooler could handle until last week. I ran into a buddy at a gas station that builds cummins. He's running a stock intercooler with some kind of huge T4 turbo. If that giant T4 works great with that stock unit I should have no need for a bigger one.

I almost forgot to mention a mod my little brother and I did that most people would probably never even notice. I'm a firm believer in the little finishing touches making all the difference in the overall quality of a truck. Hopefully some other guys doing the cummins swap can use this. Or hell send us the parts and we'll do it.
After I removed the mechanical fan from the idler pulley I realized the the threaded part the fan screws onto in permenant. I couldn't ever use the mechanical fan due to how low my radiator will sit with the body drop and how close is sits to the radiator with this long Cummins engine. So I pulled the idler pulley assembly off of the engine and took it completely apart. Grabbed a nice big brass hammer and brass punch and knocked it apart. We chucked the inner piece up in the lathe and turned the threaded part down. If anyone else does this on a lathe or even with a grinder be sure to leave the shoulder for pulley alignment. I probably wouldn't try it with a grinder Or anything but a lathe but it's your truck do whatever you want. When I went to put it back together the bolt was way to long. We had to cut it down also. It sure the front of the motor look a lot better.

I got the new compressor put in my little garage today. That was a job. We ended up having to use a bobcat to move it. I just left it on the pallet for now. My garage gets a bit of water in the floor if it rains real hard so the pallet should keep it out of the water. I had to go buy a bunch of new fittings and a rubber air hose due to the idiots that ran off with my last compressor. This thing is so tall I had to knock the header off of the garage and take the air filter off of the pump. I'd like to see some thiefs try to run off with this 800 pound beast lol.

should do the job i just wonder why you put it so close to the door instead of in the corner away from the door , it looks like its taking a big bite out of the width of the door

The garage really isn't big enough to put anything in big enough to worry about any door width. It doesn't take up near as much as it looks like in that picture. It takes probably 2' of one of the doors. Also trying to take everything out of the garage and than muscle this huge thing into the back of the garage and than out everything back in just wasn't worth all the trouble. I used it today and got 1 of my lower arms done. This is the first compressor I've ever owned that I can't out run with my air tools. It's amazing how quiet it is also. It only turns at about 1500 rpm but makes almost 20 cfm at that speed with 1 huge piston.

Nice ass compressor man
