Need some input on carb mods. necessary on my 70. It's not that big, 597 c.i.I am drawing through both barrels, and running the LP manifolds. Do I need to drill the main jets bigger and if so how big? I am running 3/8"s plumbing from the tank outlet to the carbwith inlinefilter. Will this get enough fuel to the carb without a pump? The motor is fresh & runs good, but would like to have carb close before I load it on the dyno.

Run a fuel pump just to make sure you always have fuel, that thing must really gulp in the air, I often thought of how one would run with the carb done like that.
