1965 Chevrolet Corvette - Rough Around The Edges

A '65 396/425-Horse Driver That's Not Perfect, But Close Enough

Engine :::
The first year for a big-block in a Corvette, the 396 L78 made one hell of a first impression, making well over 400 hp (an estimated 425 at the flywheel) in 1965. Only the Super Stock Hemi-powered Dodges and 427 side-oiler Fords made comparable power in those days, and they couldn't handle worth a darn.

Where's The Radio? Designed for performance over luxury, Gregory's Sting Ray was ordered without a radio. The sound of the side pipes would probably drown out the sound anyway. TIRES ::: Gregory boasts that these Pirelli rubbers are made for smoking. The stout 4.11 positraction rear gears promise it. UNVEILING ::: Found in a barn under a drop cloth, the L78 still brandishes its original California plates. BREAK TIME ::: Brothers Chuck and Gregory take a break from thrashing on their chassis-on restoration.
