That's some serious airflow goin' on there with TWO 950 Holley 3-BBL's! I can see where they have been somewhat converted into mechanical secondaries with the infamous screw placed into the Secondary throttle shaft linkage. That particular early-style Tunnel Ram has the reputation being explosion prone due to that MASSIVE plenum chamber. Please don't think I'm knocking it or anything, but you need to be cranking that motor over with the starter before pumping the gas pedal, otherwise that plenum becomes a giant fuel/air chamber and an intake valve hanging open (or even bent from last summer's missed 2-3 shift!) can result in a backfire of EPIC proportions that will be the subject of cruise night small talk for decades to come! By the way, do I spy a Motor Wheel Spyder center cap on the table there?
