Stock 360 4bbl intake

The TQ carb styled intakes outflow the AFB AVS style intakes by just a little bit but they are essentially the same and take manifold.

It’s best to block the eye off on the plenum floor though the outside (driverside) should also be blocked off. The egr valve is only open when there is enough vacuum to open it. Tht would be during cruise and light throttle acceleration. At wide open throttle, it closes. No vacuum. If you have the egr valve intake, just leave the valve there and disconnect the vacuum line.
