1965 is an important year for Corvette. A long desired and needed upgrade - disc brakes - became standard equipment. The good news is that they appeared on all four corners, not just the front as was common practice of the day. Racers were particularly happy with this latest development as they had long been suffering with drum brakes. Although special sintered metallic linings had been available, fade under racing conditions was still a problem. Jaguar had been offering four wheel disc brakes on their more expensive E-Type and it wouldn't do for the Corvette to be playing second in any area. The unloved drum brakes were still available as a deletion credit (RPO J61, -$64.50) and 316 1965 Corvettes were so equipped.

A new Corvette era was ushered in when a leading edge class of engine, fondly known as the "Big Block" was introduced late in the 1965 model year. At the time a huge horsepower race was taking place industry wide and the 396 cu. in. Turbo-Jet was the Corvette's ticket to the party. Rated at 425 hp, it furthered the Corvettes' Bad-Boy reputation. It also represented the first time a Corvette motor was rated at over 400 hp.

Most of the horsepower advantage in the new motor could be found in the design of the heads which were nicknamed "porcupine heads", a reference to the way the valves were located at odd angles similar to the quills on a porcupine. The entire big block Corvette was thus sometimes known as the "fiberglass porcupine". The physically much bigger engine required an enhanced cooling system. There was another drawback; approximately 150 lbs. of added weight, all of it on the front wheels. The weight distribution changed to 51% front / 49% rear, a handling disadvantage compared to the better balanced small block alternative.
