1968 Chevrolet Corvette - HS68VT
|
Back in '68, the RPO L68 400-horsepower 427 was a $305.50 upgrade over the standard 300-horse 327. This one was rebuilt with an .030-inch overbore, L88-grind camshaft, forged steel crank-and other hardware that pushes its output past Chevrolet's advertised power figures. View Related Article
