how good do ya think this will work
i have a 75 351w out of a truck + the c-6 too, the motor is fresh but stock except for edelbrock performer carb, cam + lifters, mani, gear to gear drive timing,+ 50-150 shot of giggle gas,headers,billetproof dist,msd box, super coil+ a old mc,culloch super charger (first paxton) from an old desoto! i made a hat for the carb + ran the vent tubes out thru the hat(so i dont press, bowls) i have not had a chance to run it yet for i have not finished the car its in, how good do ya think it will run? i've got this crazy idea to try to run the blower off of a 12v motor or a elect clutch pully so i can turn it on + off as i wish! think that would work? i just bought a 78 bronco that i think im gonna put the motor in + build a diff one for the car( i know about the trans issue im gonna change output shafts + use the 351w's trans it has a shift kit + stall conv,) back to my question how good do ya think this combo will work

The motor will indeed run when the blower isn't turning. However, the strain (current draw) on a the electrical system would probably consume as much, if not more, power from the motor to turn the alternator(s).
A turbo would probably be better option for what you're trying to achieve.

From what I understand...any kind of supercharger will prevent the engine from running should the belt break and the supercharger stop.
Are you thinking of the electric superchargers? Those are a scam...

If the compressor rides on its own belt/pulleys then the engine will still run. I've thrown a belt a couple of times and was able to drive it back home, without any issues.
I'd say the engine will probably still run if the compressor rode on the same belt as the accessories, but there are other problems associated with that if the belt comes off: no water pump, power steering or charging system.

Perhaps it only applies to non-centrifugal superchargers then? I swear one of my friends called me one morning and said he blew his supercharger belt and it killed the engine, new belt and it started right up. I must be mistaken.

the Mc,Culloch supercharger is a paxton type, ( paxton bought out Mc,Culloch ) what i was thinking about doin was taking a magnetic pully off a A/C compressor + modifying it to fit the supercharger to ingage + disingage the supercharger with a flip of a switch! , i'll have to take the belt off it + see how it runs after i get it back together? i think it would be cool for one, second i could just run the blower when wanted!, if it works? ya know if it choke's it out not running i could fab in a electric cut-out to open up when the charger is off, that way it gets the air it needs???? any thoughts???

Ah...well learn something new everyday. Thanks guys.
I agree with jimdandy, go for a clutch, they're not too hard to setup, they're easy to find, and they're about the only way you'll make it stay engaged. As he said, electrics are going to be a no-no.

Here's my view on this. A supercharger has very little parasitic loss under normal driving conditions, so there is really no need in using a clutch to engage the compressor. One thing I see happening is the shock that is put on the crank shaft when the clutch engages the compressor, this could snap the front of the crankshaft off and that would not be a simple fix. On a belt driven application, under heavy throttle conditions (0-3" of vacuum), the bypass valve shuts and that's when the blower creates its boost and the only time it is actually putting a load on the motor.
