Ok, so now that I'm getting my 74 Duster back, I plan on going forward with the supercharged Slant 6 (225 Super Six).
I've got most of the important parts figured out, such as the lower pulley (Slanty's can use Chevy 3 bolt crank pulleys), I've got a manifold design going, and the location of the fuel injectors figured out.

But before I finalize the manifold design...
Should I use the Eaton M90, or the M112?
Or do you more experienced Mopar guys have a different Supercharger suggestion?

And yes, I really want to go with a blower. Turbos are cool, but I plan on auto crossing the Duster, and I want the blower for low end torque. Plus I think its better, considering max rpm stock is....4500 I think?

I'm open to any info you guys can give. I'm still in the research phase.
 
No help here...other then good call on the blower
I just love the looks of them

Will you have an offset hole in the hood for it?

Actually I won't be punching a hole in the hood. The blower will be mounted on its side,and remain hidden under the hood

AussieSpeed B&M 144 and M90 intake manifolds. An M90 will support upto a 5.0L engine.....

See the above picture of the side mounted blower?
Basically that, but the injectors angled to aim at the back of the intake valve. The injectors and fuel rail will be mounted to the intake manifold, much like any modern vehicle

Are you making your own manifold? It looks like the side mount one was custom made.
I really like that side mount design. As for which blower, I would personally go with the 112 just because its bigger. Adds a greater "Oh sh*t" factor when you open the hood if you have a big blower under there :D

I will be making my own.
And if I can get a 112 for a decent price, absolutely
 
Turn a supercharger sideways, will it still oil properly?
 
is it oiled through the engines oil pump?
as in 20-70 PSI?
