[DonC]

428 in front of a TKO 600 with 0.80 fifth in front of a 3.07 rear end but with 17" wheels (better selection of tires). 22 - 2300 rpm at 70mph. Wind noise and exhaust noise are about even on highway.
A very tractable combination for a cruiser and can run in 4th comfortably down to 30mph with the big block "grunt" available.
