What a 1968 340 manual transmission cam idles like in a 1969 340


Idling about low at 750 or so. This is with the VOE mufflers in the open mode.
It has stock exhaust manifolds and 2.5" pipes, both sides, running into a Dr. Gas X 2.5" junction and then into the mufflers. Tailpipes are stock, with the original small diameter inlet chrome tips.
