Re: help! correct redline tach for 69 396/325 4speed
I thought it was all 1969 Big Block Hydraulic lifter engined Camaros with MANUAL trans.were built with A.I.R.
And ALL the Solid lifter 1969 Camaros with Auto & Man. Trans,got A.I.R. also.
Meaning the MANUAL trans. was the deciding factor for the Non solid lifter engines,because the drivers feathered the clutch,& had a Higher possibilty of Pollutants.
