1968 Road Runner '383' vs. 1968 Chevelle 'SS 396'

Head-to-Head

The 1968 Road Runner '383' walks all over the
1968 Chevelle 'SS 396' 'L-35'.

With each running 3.55 Gears, it wouldn't matter
which Transmission was backing their respective Engines.

With connections, some guys were 'lucky' enough to get a 1968 Road Runner '383' with a 'Regional Office' approved set of 3.91 Gears.

With 3.91 Gears, the Road Runner would still handle a
SS 396 'L-35 that was backed with 4.10 Gears.

Torque-Flite A727-B
The Road Runner '383' had an excellent 10.75" Torque Converter

Also, the Governor was a higher RPM unit which allowed for better 'heavy' throttle shifts.

A-833 4-Speed
The Road Runner '383' had a Type-1767 11" Clutch-Disc, which
was a fairly durable unit.

The Pressure-Plate was rated at #2181 lbs., and it was well-suited
for Heavy-Duty street use.
