I owned a Griffith 400 w/ 271 HP 289 engine from 1966--1968. It came with 185-15" Dunlop SP tires which were as wide as possible without rubbing the body or suspension upright. Way too narrow for the engine power. I won quite a number of 2nd and 3rd place autocross trophies, but never got a 1st place because of spinning out. The car came with high 3.08 Salisbury diff gearing, which resulted in a slower take off launch. With a 7000 rpm redline, I saw 70 mph in 1st, 93 in 2nd, 115 in 3rd and 135 in 4th, before chickening out. The front end was pushed way down from air flow pressure and the rear end was VERY light and was becoming unstable. Never went that fast again in a car without a rollbar!
