New to the forum and new to the slant six, not at all new to mopars having darts, dusters, cuda, challengers durangos dakotas and rams.
I have just recently picked this truck up, it was mostly stock. The truck had been sitting on a car lot for over five years, I was able to secure it and took it home. The steel wheels and tires were worn and rusty. I had a number of little things I needed to do to get it running and started just driving it as a daily driver.
I soon got bored with how slow the stock engine was , at 102,000 miles it runs well , but when I added the big tires and Centerlines it looked fast and needed to be able to atleast get out of it's own way.

I secured the Ford Eaton off ebay,converted it to sealed rear bearings and made it a blow through supercharger. I machined the adaptor for the rear and a lower plate for the intake,then added the 500 Holley. with the 3" pulley I get 5.5lbs of boost and nearly 28mpg hiway, with the 2.5" pulley I get 8.5 lbs of boost but only about 20mpg, but the power difference is big! Either pulley gets tire spinning power and smiles for miles!!

What have you done about the coating on the rotors getting eaten by fuel?

That's awesome BTW!

I used oven cleaner , sprayed it on and coating came off with very little effort. 00 steel wool polishing,then added new coupler, front bearings and seals,snout bearing and seal 17x24x5 rear seals and new 17x24x20 open needle bearings. The rear plate I machined a cavity that allows a larger grease capacity for the rear bearings. So far I have a few thousand miles on the setup.

That is freaking awesome. I wish I knew more about forced induction.

Besides mounting the blower and new carb, what else was done to the engine? What was done to the carb? Did you really mount that setup on the factory aluminum one barrel intake? Did you modify the intake at all?

We want details! And a burnout video!

I stripped all the emissions from the engine, run the exhaust through a flowmaster muffler, changed the plugs and oil, mounted it directly to the one barrel intake, the holley 500 was right out of the box, tuned a little and runs well, since there is not boost bypass I have the idle mixture a little rich . I will see what I can do for a video. the lower plate is machined with a large opening to improve flow,and the rear of the outlet has been ported a little.

I have less than $450 into the blower project.

future plans are a new ignition, headers and a clifford intake.

Dang, I might have to give this a try at some future date. Stock distributor? Stock timing curve? Stock cam? What was the original application of the supercharger? Is it an Eaton M90? I am assuming you are not runing a vacuum advance system on your distributor?

stock distributor, I run the timing a little retarded. the blower is a eaton m90 from a thunderbird.

Very nice...
Fwiw..ive done a few eaton draw through setups..no sealed rear bearings..coating disolves after a while..but it doesnt seem to matter..i ran my last blown geo on e85 from anywhere between 12-18lbs boost for over 10k miles..with e85..the blower and intake would frost up on hard pulls! Boost is great..my latest slant will be a remote mounted m90 blowing through cv's..ill post a thread as it develops.

Welcome to the site, and very cool project. Nice to see another tight M90 project out there. Al Toews in Calgary, AB has another nice setup with EFI.

Best,
Lou

I am very interested I this setup. I may change direction with the motor I am planning to build for my brother's Duster and make it an MPFI supercharged system.

I do supercharged projects at my real job, they usually have a larger budget than mine. Here is an 8-71 Hemi , that will soon be a Challenger.

I wanted my M90 setup to be similar and reliable to the other wet superchargers, this is why I added the seals to the rear bearings and stripped the coatings, not want to leave anything to chance.

That is cool, but not as cool as a blown slant. My brother agrees- we are definitely going to pursue a supercharger for his Duster. I just need to teach myself how supercharging affects things like timing curves and fuel mixture parameters. Then I need to get the pieces and machine and assemble it all. On as cheap a budget as possible!
