It would have been soooo easy for them to have made the Ultramatic a three speed, have two gears numerically higher than 1:1, and use the direct drive clutch as the 1:1. You could have had a low 1st gear for quick take off, a decent second gear, then it shifts to Direct for High gear, 1:1. Would have been easy.

If Chrysler had the "Half A design", being half the suspension of the '55-'56 Packard, and seeing Chrysler totally out performing the GMC/Ford, Packard would have been completely superior to ALL domestic cars. I bet Packard would have been a killer on the NASCAR/ Stock Car circuit with the V-8 perfected by '56 or '57 & torsion bar suspension. They might have dominated the circuit like the Hudson Hornets did with the low center of gravity.


I always thought that, too! Sadly, a race driver with real experience with V8 Packards, even running at NASCAR as well as dirt tracks with a '55 Clipper Panama maintains that you just couldn't get the T-L set up right for optimum performance. The Panama retained its spring suspension. (See Pics at right of the late Jack Harlin's #50, if they are still there. Otherwise, go to the Packard Pictures 1955 folder.

Below is Jack's verbatim answer when I suggested to him that T-L would've been the hot setup at the track.

THIS IS LONG BUT GREAT HISTORY FROM THE HORSE'S MOUTH:

HA I wish U luck in finding a Packard that raced let alone one with torsion Hope U do find out as I would like to know also.
We took the TL 56 to Darlington & it was a joke more or less. To give U a run down on Packards in racing. Since I wasnt doing a very good job we got Buck Baker to take it out. After 8 laps he brought it back & said if U guys make the race Im going to give U all the room I can & get away from it. We lowered the rear, cut the TL switch & I got black flagged.
Pit boss, Brunner, said the rear springs were broken, fix or leave the track.When told no springs on it he looked underneath . We leveled it out & when it raised up he thought we were a bunch of Yankees that modified a car that wasnt stock & red tagged us. They called the P dealer in Atlanta, to find out if a production car, or we modified it. Imagine now this was NASCAR not a local track. Any way no other Ps at that time were raced. Remember they were still fighting the Mason Dixon line back then & Junie Donlevy from Va. was furthest one North besides us from Harrisburg, Pa. This was a "good O'le Boys" group then.
I only told U this as to finding any that raced. We had the only P in local races also.

The # 50 had regular suspension. I think I mentioned we installed heavier coil springs from a Henny ambulance.
We bought a totaled 56 Clipper 2dr. HT with TL to race. Didnt matter what we did it just wouldnt handle. Both of us been in racing since 1947 running Ford coupes, & no stranger in setting them up, even though each required a different approach.
True torsion in race cars have 2 bars in front & rear, mounted side to side, & adjusting them at the opposite end. In other words the bar for RF wheel is adjusted at LF end of it.
If U adj. more weight in RF, it changes wt. in LR wheel also, & LF gets lighter along with RR. Thats why a scale is used under the wheels to go back & know what U have. Different tracks different setting like gear changes. With 8 to 12 lbs air in tires plus stagger on rear tires it becomes a science getting the proper balance hard to tacky tracks & choosing all these settings for last laps of race cause tracks change during the race. NO such control Of Packards TL A lot more involved than this but U get the idea. Jack
