While in the process of researching carb flow for the 1904s, I thought using 2 of the Falcon 144cu-in carbs (@130cfm each) would be a better choice than 2 used on the 223 (@170cfm each). The idea being that it would be better to be undercarbed at 260cfm than overcarbed at 340cfm. As I'll be limiting top RPM to around 5000-5250, I doubt very much that 260cfm will be undercarbed even with some head work and a cam for higher RPM based on some of the modeling programs I've used.
To anyone who might have set up a dual carb intake, any bits of advice regarding jet sizing or increasing the ported vacuum signal for the distributor?
I know the spark control valve can be removed from the carb at time of rebuild and the distributor has already been replaced with the 300ci BB unit with vacuum currently plugged into a manifold port.
Also downstream a bit will be an MSD 6AL ignition system.
Any and all guidence is appreciated!! :thanks:
