I should talk, I'm running 3 500cfm 2bbls ( I won't know what they actually flow for a few more days, but its more than they did stock), solid roller and ported Indy EZ's on the street.
I had a new fuel tank made that holds just under twice what my stock tank held. That comes in handy with carbs that mimic flushing the toilet when you open them. An automatic overdrive with lock-up converter is a nice feature to have with a high-stall converter too.
