which blower hat to choose?

Have you checked the prices in blower EFIs? Unless your budget is unlimited it would maybe better to start with carbs. I'm a dealer for a couple on the manufactures of EFIs and the price is not for sissies. As far as double blowers why not consider a "loose" and under-driven 14-71 for your motor.
The Hoosier tires will be an "adventure" if you get the horsepower that I think you'll have. By car gets them loose in 3rd before you get to the secondaries. I believe that you can put a blower on anything if you have the right builder working with you.

If I was even considering double blown it would be a side by side (which i wouldn't consider).I damn sure wouldn't want them stacked for 1 stupid looking. 2 you would be running the bottom blower waiting on fuel from the top. 1 blower beats the air fuel charge enough via heat, much less sending it thru a second blower running dry(more heat). I'm sure you could ( I mean someone could) plumb in fuel on the bottom blower somehow, I think it would be a nitemare . but again I think this was a pipedream anyway

Definitely doesn't look right

I can see all sorts of issues with double blowers stacked. Beyond the fact it would be insanely tall, there's belts to drive both and heat from one blower being introduced into the 2nd blower and building up even higher temps.
I'd also be concerned with head gaskets holding the amount of compression such a system can build, unless you under drive it so far that it is just for looks.
Sorry, but it just sounds a bit nutty.

Double stacked blowers kinda go with the "bubble top" crowd! You can take-it from there.
