SBC 671 blower, What Distributor are you using?

Curious to know what distributor you guys are using on your on your SBC with a 671 Blower? are you using a boost retard? Vacuum advance?, Im sure my HEI isnt going to fit.

 

Get a hold of GMCBubba. He's done a couple of dizzies for me, both hei, and they work great!

For my tri-power, he did an old school small cap Mallory,external coil, and converted it to hei. It worked great, and would work with your blower.

Price is good too!

 

I've used MSD (no btm) on one and a GM dist. w/Crane XR-i drop in points conversion on another. Both mechanical advance only, all in by 2000 rpm, 34 deg. total. Worked great, I've also heard of using the vacuum advance and plumbing it to the manifold, yet to try it myself.
