References 2 different GM-produced motors. The pontiac version was good for keeping boats from moving around when attached to the end of a chain, while the Buick versions made 400+ hp and 500+ lb. ft. in stock form, or in modified form (like the one in MY pimp-455 ride) can produce in excess of 520 hp and 598 lb. ft. WOOT!

Ricer: Damn boy, thats a big-455 motor, how many liters is that?

Buick: Well, its 455 cubic inches, which is 7.6 liters for you dumb-45535 who can't convert to proper measurements
