I am considering a multiple carb setup for my '55 TBird and am wondering about hood clearance.  Will a triple 2V or dual 4V setup clear my hood?  No Teapots please.  

What's wrong with using two Edelbrock 500 cfm, or two Edelbrock 600 cfm carbs?  They look good, work good, don't leak fuel after sitting, are relatively inexpensive, and fit the manifold without much ado?  A 500cfm 2V will not give you the gas mileage that a 500 cfm 4V does simply because of the size of the venturies.  Two of them would be worse, and the spacer needed would increase the installed height.    Joe-JDC

Familiarity I guess.  I've had a few Ford tri powers and they are sweet looking and running set ups.  I have never played with AFBs.  Most of my experience has been with Holley carbs.  There's a first time for everything.
