I could see different bank to bank AFR on a long ram as it basically turns the engine into two four cylinder engines. Getting 2 carbs to make identical fuel curves on what is effectively 2 similar but separate engines would be quite a challenge.
I don't think the balance tube would make any difference to speak of on this as far as AFR is concerned at least above idle.

Yep you would be correct, but a single plane intake only needs 1 o2 sensor.
Apparently I thought I was quoting BBM's post.
Oops..
What kind of induction is Bad340fish running?
Kevin
Single plane indy intake for W2 heads. Its got lots of camshaft so it has a lot of reversion which makes a mess of the intake at low flow scenarios. Its port fuel injected so the fuel part is consistent but the airflow will cause variances. I knew that happened and have seen several cases of it but I didn't realize it would be so much. The amount of fuel feeding the two banks can be very different at low rpm and low load. Like I said before once you get tipped into the throttle and the RPM comes up it all falls into line.
Joel, they make a nice digital gauge that runs two sensors but that may not be the look you want with your coupe.
