Anyone Running A Multiple Carb Setup

[Anonymous]

Just wandering if anyone's had any luck running a multi carb set up on their crossflow. They look so cool. And if I'm gonna get away with running a hot rod six in Dallas TX. It's got to be cool or extremely fast. 8)
Preferrably both.

What sort of economy?
I am thinking of either twin or triple SUs on a custom manifold. Sus are great and they look good too.

About 27mpg with a .68 overdrive and a 3.00 diff gear on an open road trip. Also , 17-20 mpg in town depending how you drive it.
Further jetting;
P.S; idle air bleed is .65mm and pay careful attention to progression hole sizes and location for good economy in cruise.
Good way for jetting is to use an O2 sensor and mixture gauge in the dash.
Doing it without this or some other gauge will cause you to tear a few hairs out trying to work out the spot on jetting for multiple carburettors. Take the easier route!!!!!!
