Jon, What has to happen to a stock carb for blow through to be effective. I don't really have plans to put a blower on my new engine but just for grins I'm wondering if I could. I have a 400 CFM Edelbrock on a Clifford intake, lumps, big valves, 500 lift cam, flat top aluminum pistons.


Typically, there are three issues:
(1) sealing all areas where fuel might be blown out (throttle shafts, pump shaft, idle mixture screws, etc.)
(2) modifying the float to not collapse
(3) a "reference" line to the fuel pump, making the pump variable pressure.

Good carburetion is fuelish hot air
The most expensive carburetor you will ever buy, is the incorrect one you attempt to modify!!!
