There's a reason few have installed that on modified '56Js. When you figure out how to do it, please share step-by-step with photos.

Re: What about the 25K 105mph V8 Patrician?

Slightly OT, but the first German Autobahns were proudly built straight and flat. Those were the inspiration for the US Interstate system.

When driving in Europe, one always could make a top speed run somewhere. I had a rented BMW going north on a beautiful new Autoroute in France. It took me a while to realize it had been purposely built following the contours of the rolling hills, with never a straight stretch anywhere. This effectively prevents high speed runs.

If you haven't done it already, a tune-up begins with replacing the ignition points, condensor, rotor, cap, plug wires and spark plugs. All these being new and adjusted correctly will go a long way toward keeping it running at idle.

Re: Type of gas and whether to use lead substitute?

Don,

Octane was definitely a thing in the 1950s.

Quote:

In 1956 Sun Oil opened its first custom-blending pump in Orlando, Florida; from five grades of gasoline, customers could select the one that best met their car's octane needs and the pump would mix it then and there.

The blend could be chosen from 100% regular to 100% premium; no new news there, but it could also dispense 75-25, 50-50 and 25-75 regular/premium.

Wondering what the community consensus is on octane of gas and whether to add lead substitute for the 56 V8 engines with 9.5:1 compression?

My '55 352 runs just fine on 87 Unleaded. Previous owner of 10-plus years used the same.

World's of difference between a 7.8 compression '55 352" and a 10:1 '56 374". The '56 with 9.5 is in-between. I've seen some with piston tops showing severe detonation effects from running cheap gas. No more miles than hobby cars get, go with the good stuff and keep a close watch on ignition initial timing settings.

Re: Twin Ultramatic Lifespan.

As I've gotten into electric cars, I've talked to GM engineers on the project. The prime directive was the ability to go from an existing GM car to the Bolt EV without any special training or knowledge. It had to drive like any other GM car.

That some TUs could be feather-footed up to reasonable lifespan is an anomaly. Most owners expect the car to tolerate their driving style; not that they have to worry about it dying under them.

Yes, I know first-hand, because in 1963, my parents traded in a mint condition 1956 Hudson Hornet because of two TU failures. I later saw it sitting on top of a pile in a local wrecking yard.

(To this day, I still consider those '55-'57 Hashes the ugliest US car of that era.)

Ross's point is well taken because with the increase in power the transmission wasn't changed that much so it was like putting a 120 trans behind the V-12. But the trans needs to be in good condition to use Drive. I was never a lead foot with those cars and I always accelerated moderately until the thing got into direct. Then I would gradually increase the throttle. It's a habit I never got rid of and still use it with my modern car.

For true. The TU was a fragile piece which few shops knew how to rebuild, much less improve where needed. That weakness caused many an otherwise perfect Packard, Hudson, Nash, Studebaker Golden Hawk to be sent to the wrecking yard.

Not many owners were willing to own a luxury car which couldn't be driven normally.
