If a streeter;
If you have a manual trans, I highly recommend to try and keep the AirGap. It will allow your engine to idle down further before running into slow-driving issues.
If your cam is between 240 and
[email protected], a dualplane like the AG will definitely pull up the bottom end. That AG helped make a torque-monster out of my 10.7 Scr/367 with a 223* cam, (alloy heads).
My engine is now running a 230/110 cam, and with the AG, this engine will idle down to 550 rpm=4mph, in low gear (manual trans), pulling itself on a flat, level, hard surface. So I vote AirGap.
