Tiny E,
I stumbled upon another GTO site with some other performance tests done back in 1968.
Hot Rod Magazine tested a mid-year 1968 400/360HP 'Ram Air I'.
4-speed, with 3.90 gears on G77 x 14" tires.
In stock trim,,,,
14.25 @ 99 MPH
With 7" Casler Slicks
13.85 @ 102.13 MPH
Also, John DeLorean pounding the 'Endura' bumper with a sledgehammer!
