if i remember correctly the Magnuson aka Edlebrock supercharger is way more advanced. the vacuum operated bypass allows for fuel economy near non supercharger levels. reading through my old Car Crafts and hot rodders, thos things made more boost at less temps because of the rotor design, thus leading to more power.

oh and if you have or can find one on the cheap. a good double pumper carb is the way to go for fuel delivery.

The big ones will make about 3 times as much power and usually require 2 carbs. You can buy a top plate to accept one carb but that would look funny on such a big blower. The small blowers don't have many choices of pulley sizes so you are limited to the amount of underdrive/overdrive you can achieve which directly relates to the amount of boost or power you can achieve.

The small blowers typically only produce around 5-8 lbs/boost while the larger ones can produce anywhere between 5-30 lbs/boost. The big blowers aren't for the faint of heart.
 
Hell,,,get a couple of them......:bow::bow::bow::bow:

Warning the following contains a metric S#$t ton of opinion. probably worth what you payed for it. :haha:

Everyone here has good points but I would go with a whipplecharger based sytem. All the instant power of a roots type blower and WAY more efficient. Think of it as the next generation of roots type blowers. More boost with cooler air charge and less HP to drive it. They also have inter-coolers available for them.

I have never been a fan of centrifugal superchargers as it is basically a belt driven turbo. They do work, and work well but you have the disadvantages of a turbo and of a supercharger at the same time. If I was going to give up the low end grunt of a supercharger I would go straight to a turbo and loose the drag of the belt and use the free exhaust power.

eh that may be a bit much for me, i know they say you cant have to much power, but my carb is brand new and im really not wanting to invest that much money into a small block. it would be great to run dual carbs and a big blower but on a mild 350 that im wanting to DD and trail ride, is that really necessary?

now when i build the burb or the CC with the big block then that might be exactly what im looking for :bow:

Both blowers and turbos are good for top end HP but for a truck neither is really good, torque down low is what you want and you wont get that from a blower or turbo. I'm not saying that they don't make power at lower RPM's but not in the low range we need it.
 
4x4high is right though blowers do make good off idle torque, you would probly find more benefit in building the motor. Around 2500$ will build you a 496 (the 383 of big blocks) with 600+ lbs of torque 500 ish hp. Though you might have to do a good bit of craigslist/junkyard/swap meet wheeling and dealing.

If it were me personaly i would just stroke the 350 out to 383, then get a set of thos cnc ported AFR heads with a mild cam. should easily be able to reach the 450tq 380-400 hp
