NSS Inline 2x4 Intake
One item worth mentioning is some of these 'flatter' floor intakes can accumulate fuel and under certain conditions will backfire. It's a good idea to install a backfire valve to protect the investment. And the larger plenums really respond to the pumpshot of a holley carb. The inherent stumble is reduced with a strong signal to the carbs. We've had decent luck with AFB's on the modman I did but I'm sure it'd improve with some holleys based on A/F data.
