408 stroker vs procharger 360

Yeah it's all blow through. If you run this setup carbureted you'll have to get a modified carb that has throttle shaft seals and composite floats. Brass floats will collapse under boost pressure. I got mine from a place in Colorado they take a Holley 4150 do the above along with taking off the choke horn so the air is less restricted coming through the carb hat from the Procharger. If you go with fuel injection it's different story. You can also run slightly higher boost safely all factors being the same with fuel injection because of the way the fuel is dispersed.
If you have room you could do an intercooler too, but because of space constraints on the A-body and not wanting to modify anything I ended up going with water injection. Which is a very good safeguard against detonation. If you go with a procharger I would highly recommend http://thesuperchargerstore.com Terry and Bob have been boosting mopars for years and years and they know their stuff.

Any other questions let me know.
