Snowmans idea for race gas was using a separate fuel tank & was to put 91 octane in it for 15 +psi boost pressure w/no intercooler & no timing retard devise. (that was the race, 91 octane race gas configuration )
The original tank was used for 87 octane fuel & limit the boost to 12+ PSI.
How much boost are you looking to go to? Electric choke just means it does not need you to mess with it manually. More of a hands off approach.
A manual choke, gives you the choice it your engine needs a choke for cold starts. Cold weather starts. A manual choke allows you to see if the engine needs more fuel when boosting by closing the choke a bit & see if the engine likes it by basically enriching the A/F mixture. Or it it falls on its face because it is way too rich by closing the choke a bit.
The distributer looks nice, hope it works out for you.
