Sorry I haven't been on lately, I recieved my new Kirby head and am working on my 37 chevy with a new intake with carbs, and new exhaust etc.
Tom is correct a small holley 4bbl would work better more driveable, with such low boost on a blow through all you need is to get the mixture correct and use plastic floats that will not crush, no other mods needed, but you need to boost reference the fuel pump to keep the fuel pressure at 6 lbs plus boost pressure. You can run stock timming no blowoff valves etc.
On a draw through you would need to reference the power valve but not on a blow through. Run a pipe from the compressor to the carb and floor it!
Good Luck
Harry
