Sorry digging this up, I am running a chevy 350 with a old B&M 144 with a 830cfm carb. It's not streetable due to the gas milage but everything else is holding up fine after 5000 miles of road racing abuse. Of course the motor was way way over built for the amount of boost that is running through the motor ~5 pounds right now. I have the build sheet somewhere on my computer but to say the least the motor runs about 7:1 and does not ping on 91. It loves 106 though. I am actually putting the 3 pound pulley and some ~3.3 gears in it this weekend so that it gets better the 7 mpg.

Things to look out for, make sure that you don't have any flow restrictions, your supercharger will creep up the recorded boost as it builds at higher rpm's. So now you have super hot compressed gasses which robs you of a lot of the power that you were making with the boost, and two you will have a heck of a time getting the idle set right, as some superchargers cause a vacuum condition on an idling motor the idle parts in your carb flip out.

There are ways around this but they are application specific.
