Opinions on 6-71 Blower needed. Run it? Sell it? Let me know.

[ChargerRon]

As many of you know already, I bought a 1968 Charger with a numbers matching small block engine that I am building to use as a daily driver. I have never ran a power adder before,  but recently I acquired a Dyer's 6-71 supercharger for a 440  and was curious if you guys/gals think it would be possible/reliable to have a blown big block as a daily driver or if I should just keep the small block? If I sell the blower, I plan on building a stout small block for motivation. If I decide to sell it, what do you think the blower is worth being a used unit. It is a polished unit and is in very good shape. Let me know what you think. Thanks. ChargerRon.

i think a blown 440 would be awesome to drive daily.  expensive but awesome.  If i was you id slowly build a 440 for the blower and if you have to drive the charger daily, but look for a cheap car for a daily driver and put the blown 440 in it.

Or you could just get a different intake manifold and go this route...

Possible yes, practical no, a shitload of fun for sure!

I think if you were starting from scratch and did it right it could be practical enough.  Too many people have tried to build blown motors for the street over the years and have them built into fire breathing monsters.  Make you component selection realistically and you could have something that is no less practical than many other high performance engines.

6/71 is not all that much for a 440+ cube motor.  You would twist the crap of the supercharger to get much boost for what you want.  Or you just like the look.  Harder you turn it the more inlet air temp you bring.   Personally I would not run a 6/71 on anything other than  a 350 or less cube motor.  But that is me.

I say put that thing on your small block.  Only the intake is different and you may need a different snout on the supercharger.

I don't think a 318 would last very long with the boost from a 6-71 on top. Honestly, I am considering putting it on for the look and sound of it more than I am for horsepower.  It doesn't have to be fast, it just has to look fast.

Ummm K, you do know you adjust the boost by the pullies right?  You do not have to spinn the crap out of it?

So you could run it on a stock motor with very little boost 4lbs or less and should not do much to hurt your motor, would maybe run more efficient.

If this is truely how you think, then just BOLT the thing to your hood and install a gear drive on yer 318........... and then have fun getting your doors blown off by 350 Novas.........

it was fake in the movie

Very true if you just want the whine of a belt or gear, get a gear drive as mentioned..... not worth the chopping up a hood for.

Crap I want one!

I'm more a fan of the screw-type blowers they've been perfecting in the last decade or so.  The case size is smaller and the power characteristics are much more street-friendly.

   

[ChargerRon]

Well fellas, I guess that settles it. It is now for sale. I think I'm going to run a procharger on the small block.  I can get the sound I want, it stays under the hood, and I get extra horsepower.  Thanks for the opinions.

Actually no... it was real in the movie, just fake in real life. But that's what you meant.
