How will it work? I know it isn't the most optimal setup, but it looks like I'm going to be building a motor and I already have the radix blower. I can't afford to by a turbo or bigger blower right now. Motor will probably be forged with a cam, no head work yet, I just can't swing it right now.

Would I be better off just building it as a 6.0 again?

 

which magnacharger do you have?

 

The way I look at it is 4 psi is better than no psi at all.

 

112 sound right?

 

Yea the 112 is the smallest level, but like Ky said some boost is better then none. I don't know if anyone has put a 112 on a 408?

 

mnc5 did a 112 radix on a 427 some time ago, it can be done, just not optimal.

keep the compression up and good fuel, boost will be there just don't know how much.

And a big "Roger" to Roger(kysilverado) Boost is BOOST! the tq will be off the hook!!!!

 

im with these guys, some boost is better than none..
id say run some meth through it to keep intake temps down and for fuel ofcourse..

 

I put a 1900 on a 408 and it works great. Just go with the 112 until you can afford the upgrade. I made 727 hp and 653 ft/lbs at 6 lbs with some trick mods. Here is the dyno chart.

 

How did you make 727hp with just 6lbs of boost?

 

I don't see a downside to running your 112 on a 408. Just go into it knowing you'll be OK with whatever boost it gives you and enjoy the ride!
