hp wise, a '78 W72 in stock trim was rated the same as the vette (and that's gm rating and we all know they fudged those) the pontiac made WAY more torque.

let's get technical.

If you want to use the "my car is faster" mentality, a '70 RA IV car would destroy a '74 SD any day of the week.

Most road tests of the era had 78-79 400/4 speed cars running around 15.3 which what many std GTOs, SS396 Chevelles, 390 Stangs, and 383 Roadrunners ran in the late 60s.
