<VV> [fastvair] Best 2-Carb Setup

Build a couple of 90 degree adapters and use a pair of SU carbs. Or the 
knock offs like the early Datsun Z cars used.

Hi,
 
I need to set up an engine on which, because of space constraints, I 
can use only two carbs; one on each head. (This is going in my 66 912 
Porvair.) My intention is to use 140 heads with one carb pad on each 
head blocked off, combustion chambers cleaned up, slant exhaust tubes, 
and headers. Currently, I run a Rochester 4-barrel on a two runner 
manifold, but the driveability is poor at best (typical tip in 
problems). My choices for the future are these: 
 
- Keep the current system and completely rework the carb or replace 
with a Holley.
- Replace the 4-barrel with a two Rochester H carbs that have been 
modified for performance.
- Replace the 4-barrel with two progressive 2-barrel carbs (Holley or 
Weber).
 
I'm not interested in fuel injection at this time. My goal is better 
low-end performance while still retaining some high-end performance. I 
use the car for city driving and would like to set it up for 
autocrossing.
 
Please share your thoughts on carb ideas, what you have used, and what 
your experiences have been with different systems.
 
Thanks,
Joe White (62 4-door, 66 Porvair)
