Thinking of buying a Street Demon Carb...

Over 2 pages of this and no one has yet answered the OP's question regarding choke to air cleaner clearance.
Unfortunately, I can't either; all I can say is that I've been running a Holley Street Demon on my V8 powered 47 Jeep for over 2 years now and it works great right from the box. It replaced a worn out TQ on a stock Shivvy 350.
I guess every site has to have some stroke with an opinion.
