13B 6 port or 4 port for carb
 
If one was going to go with an n/a carb build, would it be better to go with a large ported 4 port, or a 6 port? Im aware of the 6 ports ability to perform better due to the extra 2 actuated ports, but how would a large port 4 port work on an n/a carb setup? Just curious and playing with ideas in my head. Ive got the itch for an n/a build again after my last fb build. thanks for any info in advance.

why a carb? Fuel injection will give you better power and driveability. Is this a track only car?

And for a street driven non turbo, 6 port is the best way to go, but if this is a track car, you could do some massive ports and get away with 4.
