Re: 73' Olds 455.
455+ 030....trw/speed pro slugs, rod polished & shot peened, 943 forged crank (.010/.010), balanced assembly, with a Toro pan/Melling hy vol pump. The top was a set of C casting (big valve ) heads, with a bit of Mill, & a 3 angle grind/ Engal cam (.496/ .512 lift & 230 @ .050 on duration). Topped with an Edelbrock torker/ 800 dp Holley. She would flash a said 2300 verter to 3200  Fun to play with, but not very fuel freindly (6/7 mpg cruising).....yes, that ran in my longhorn.
