We are diving deep into the Evil Energy carb to swap jets, dial in the power valve, and adjust the accelerator pump squirters to cure that nasty off-idle bog.
But the real test isn't in the garage—it's on the street. After getting the tune closer, Paige takes the wheel of the '64 Chevelle for a cruise out to BradFab Garage to monitor our AFRs and engine temps. And let's just say... Brad might have instigated Paige's first real Big Block burnout! 💨 We still have a slight flat spot to iron out, and some serious cooling upgrades coming next, but this hot rod is officially waking up.
