no leakage, aftermarket Holleys can take 20 psi and have been
run at 25 psi WITHOUT a pressurized box, but 25 psi is pushing
it. Blow through is the SAFEST way to go, and just turns out
to be the easiest.

It seemed like blow-through would eliminate a lot of the problems
I read about with pressure equalization in the carb; backfire
pop-off valves don't sound too hard to do, but corrosion I
admit I never thought of.

I haven't done any serious research, since it's all so far off
right now. Trans is coming, valve cover etc when I get pd in Jan,

hopefullyt in the car before Feb!
