General Information

1966 Chrysler 300

Originally a 383-4V "TNT" car, it was bought new by its first owner in fall 1965 from Fair Chrysler-Plymouth in Sacramento, CA.

After 34 years with its first owner, it was sold in 1999. The second owner built it into its current mechanical form – nicknamed The Flyin' Whale -- in 2005.

There was a feature article on this car in Mopar Action magazine in June 2006.

The modifications were done at ~120K miles. Vehicle still has virtually all its original paint (Spanish Red metallic), vinyl roof, and interior.

It was sold to a third owner in late 2006, then a fourth owner in 2007 where it sat (undriven, out of public view in storage) for about 10 years. It was purchased at auction and revitalized by its fifth owner in 2017.

Mechanically, it remains substantially as built by its second owner. The second (builder), fifth, and current (since summer 2020) owners are FCBO members.

Vehicle performance summary: Track-measured when built in 2005 (vehicle weight ~4,500 lbs.), its best 1/4 mile time was 12.2 seconds at 114 mph, with a 60 ft. time of 1.94 seconds (using street tires).

Its (estimated by calculation, @6,500 RPM) top speed was: 180+ mph.

Engine performance summary: Dyno-measured at build time 550 HP at 5,800 rpm (at rear wheels), 500 ft. lbs. torque at 4,800 rpm, 11.3:1 compression ratio, using 93-octane pump gas. Redline is 7,500 rpm.
