yes with 5.83. The Command car had 11.00sso I would go even faster sometimes. With 9.00s on the WC52 it is still under 3200 rpms at 55 which it will do all day no problem. problems don't arise until you exceed 3200 for extended periods because on engines with crankshafts and massive as Chrysler flatheads have, the oil film on the bearings starts to thin out over 3200. they will wind up way higher but don't want to except for short bursts.
