The Tiger manual shift flywheel is smaller in diameter than the manual shift flywheel normally used on other Ford powered cars (nominally an inch). The ring gear is not shrouded by the clutch surface of the flywheel. The larger diameter flywheel clutch surface overhangs the ring gear, mandating less throw (offset) on the starter. The Tiger starter throw is the same as used with the C4 automatic. The Tiger flywheel is about ten pounds lighter than the larger more typical flywheel. Tom
