Carb to hood clearance

[DiDueColpi]

Hey Rob, That performer Rpm Airgap is a great manifold. You can easily mill the carb mount flange down another half inch.
You may even want to angle mill it to tip the front of the air cleaner down some. The Edelbrock/Carter AFB carb is shorter than the Holley and the good old thermoquad is shorter still. Use a 14" x 3" air filter housing with a good 14" x 2" element and gain another inch of room. The early points distributors are the shortest. You can buy another 1/2 inch on the electronic ones by cutting the wire towers down to the metal inserts, or convert them to the point style cap and rotor with some minor lathe work. Lastly remote air filters work great and some really nice low profile carb hats are available from the turbo guys.
Cheers
Fred

I ended up using the air gap manifold, a 14" 1.5" drop base on the bottom & a finned top (added about 1/4" of height but looks good), 2" filter, edelbrock carb & a 1/2" spacer btwn carb & drop base.  That combination clears my stock hood by 3/8" at the front.  Could of course use a 1" drop base & eliminate the spacer, but I'd already bought the 1.5" drop & spacer was less expensive than return shipping & restocking fee.
