Lynn,

I was going to suggest we hear from you, those figures fit nicely with what I've heard and although the bridge port is bigger again than the street port, I figure the bridge ported 12A might equate to a street ported 13B 41/44mm choke. Those figures with a 36mm choke is right up there at the top I would assume.

Good stuff!

The street racers Street Port the primary ports (in the center iron) and Bridgeport the end irons. Then you have some fuel mileage, better than stock performance up to freeway speeds and still a bit of a hammer to scald the unwashed in piston powered cars at full throttle. Requires two sections of TB or a 4 barrel carb.
