well, a short wheel base car with a TON of hp can be a handful. add the wrong alignment specs to the front suspension, and "stuff" WILL happen. this car only had a 440+6/727/dana 60 combo, and the below was the results. in order to fit the engine, the struts were swapped side to side, which also dictated the rack to move to a front-steer position. this caused two major factors to happen. first, swapping the struts caused the caster to go WAY negative. think of an out of control shopping cart with wobbly front wheels. second, the ackerman went way wrong, allowing the outside front wheel in a turn [correction maneuver] to sharply turn in a very decreasing radius than the inside wheel, thus resulting in a ton of tire scrub, similar to locking a tire on ice. zero ackerman would have been better, but neither of the mentioned alignment items were tried to be corrected. only the toe-in was set, but i forget what it was set to. luckily, no one was hurt, but the car was a write off. the drivetrain was later installed in a duster, and i "think" it goes [or went] mid to low 10's.

Isn't the Colt the same as the Plymouth Arrow which Bob Glidden successfully campaigned in Pro Stock? Ran 8.50's, won several events and set speed record several times.

Similar but not the same, the Colt had a 90" wheelbase and the Arrow was 92". I am not certain but IIRC NHRA allowed them to stretch the wheelbase to 99". I think all the pro stock cars are 105" now.

I believe the Arrow had a slightly longer wheelbase, better aero, and a much lighter small block in the nose.
Colts with a Hemi were well known to be "twitchy".

FWIW the heads up car we run is 96" wheelbase C3 Vette. It has been 1.08 60' 4.97 to the 1/8 and 171MPH in the 7.90's in the 1/4 so far and other than it being a totally stupid choice for a racecar it has not been an issue.
