Blower install on a small block 350

Hello all,
I am installing a HAMPTON 671 Blower on my 350 small block. Everything is straight forward but I do have one question. I have been told to have my crank and balancer double keyed. Is this absolutely necessary? I don't plan to buzz this motor too high since i only have a ten bolt rear end.

You should do that-a little back fire can screw up alot of stuff.

It'll be easier and cheaper to do it now, than it will be later when the single key wrecks the crank snout.

Also, be sure you have an internally balanced balancer. Aftermarkets are sometimes hard to tell the difference between dampeners. A 400 balancer w/ come apart. SBC's have extremely short snouts. Be sure to pin or cut two keyways. I learned the hard way on somebody elses motor, but he bought the Austrailian 400 balancer and I didn't see the small 400 engraved in it until it lunched the shaft. Its hard not to zing up a blower motor. Too much fun. Start looking for some axles now! Billy

Blower on Small Block

Thanks for all the info.
I have a few more questions and look forward to all the input I can get.
How do you all feel about installing this Blower on a .060 SBC 4 bolt main, Any special head gaskets i should run? Also i think I already know the answer to this one but here goes Gear drive my engine currently has a gear drive on it. Keep it or Ditch it? By the way this engine is in 74 Nova Hatch back.
