Actually, immediately after the war one of the hottest cars on the drag strip was the bone stock Packard 160 two door coupe. However, after a short period of speed shifting the transmissions literally blew up and the cars junked on the spot.

The 10th-11th series cars had superior enough power to weight ratios to get into amateur racing as well.

I used to have a picture of an 11th series Eight racing on dirt track and being pushed hard enough to almost lift the front inside wheel off the ground.

In the hands of a skilled driver the solid axle cars could corner surprisingly well. I knew one guy (Jake Clancy) who set a record hill climbing his father's 1932 Cadillac V-12 sliding it around turns at over 50 mph. Charlie threw a fit when he found out.

Packard power usually was achieved via displacement and too much power is lost turning extra metal in those motors.

Another problem is these old blocks have lost a lot of metal due to age and this affects things like burn rates. So about the only thing I see coming from super tuning might be a powerful explosion.

Yes, I converted a 1941 Packard Formal to 6 volt Chrysler electrics.

You need a 110-120 sedan parts car plus some ingenuity for the rear doors and especially the division.

They worked like a dream on the fronts.

Hey All,

If you get the luck to drive one of these TreadleVac with manual shift you will find that by the time you're around the block the set up is good.

The brake pedal is on the same plane as the accelerator and your left leg doesn't care about what field the right foot is moving in.

The thing works natural.

Tom Mix had both a 53 and 55 Caribbean with stick shift. And I believe he found them that way.

Years ago in NJ there was a 56 400 floating around with twin 4BBLs and factory stick shift. It was a very rough original car and probably got used for the parts.

George Hamlin has a 56 with stick shift and I was told it is factory.

I drove the stick shift Carribean and was impressed with the brawn. The car seemed more powerful than the Chrysler Hemi of those years.

However, I think that 727 Torqueflite will outperform a manual transmission even when handled by an expert.

Hi Jack:

I've seen the video on the oil tank method, and have seen tanks used to prime dry motors, but without a specification for how much oil should be flowing per minute, or how much pressure leak down there should be per minute, I don't see much coming out of it unless a bearing is falling out of the motor. Although some of the assembly bloopers I've seen (rod bearings installed backwards and what not) would have been detected via a test. I suppose it could find a hole somewhere, but the kind of problem I'm thinking about is a little more esoteric. Suppose the foaming is due to caviation because something is inhibiting flow. Suppose there is an internal restriction in the block. The flow test would look great because nothing is getting through.

I agree that more volume will certainly help, but has anyone tested the original pump to see how much it actually displaces? My reference materials state that 3 to 6 gallons per minute is required to oil an engine.

After that, the primary cause of low oil pressure is going to be leakage either in the pump or elsewhere in the motor.

That's why I have asked the machinst working on this unit here to carefully look for any flaws in the castings and fixtures where leakage might be occuring.

The high variance among these engines is an area of concern.

Okay, The original block was replaced by Packard. I don't know how many times. I only know that the present motor number is for a replacement block from Packard. Take my word for the present block. It is no good. The motor blew up.

I think the suggestions as to the length of the oil pump shaft are very good. Perhaps the unit would function better if the shaft was modified into two pieces as were Packard oil pumps in the Eights and Super Eights (scratch that, I checked and the unit is built in two pieces). The V-12 also has oil pump issues and it has a long drive shaft as well.

As for chronic rod bearing problems, well, the air sucking problem will compromise rod bearings because oil foaming is very destructive. On the present block it is curious that the bearing closest to the oil pump was beginning to spin, but if it was getting the most air then that is an explanation.

The original pump did not have the relief valve modification.

I will carefully look at the camshaft endplay because if the cam moves back and forth too much that will cause problems with the oil pump. If the camshaft is already starving for oil that will cause a compounding as well.

The rest of the unit looks pretty generic - current practices using cross bolted main bearings and block stabilizers are far superior which is one reason modern motors last so much longer.

The bypass oil filtration doesn't help either.

Hey thanks for all the input.

I'm the one who started this discussion about this problem that has been rehashed over and over again. In all of the other posts I didn't see anything about the cam plate.

I guess TSB 56T-20 was just another patch job by Packard.

I'm working on a 56 Carribean which went into storage in 1967 after a failed motor job. It already had a Packard replacement block number 2155 and is getting a junk yard block from a high mileage 400 which was beginning to spin #8 rod bearing. This will be the third block.

I advised the machine shop to carefully examine the block for any clue as to why the engine should develop low oil pressure after high mileage. But TSB 56T-20 indicates that these motors had oil pressure problems when built.

I remember original owner Clippers doing pretty well at higher mileage, but also Charlie Clancy had a Patrician with 99,000 miles on it. Perhaps there are good blocks and bad blocks as happens with other V-8's on occasion. It seems the smaller motors were doing better which is consistent with other makes.

I guess the route here is the Oldsmobile pump which probably puts out enough volume to keep the early thrust plate if the motor still has it.

There seems to be a lot of variation and the best running cars may have been run into the ground long ago and what is left are lesser cars that never accumulated much mileage.

Hopefully this junkyard block might be a good one.

Thanks for the help.

Hi Folks,

I am looking at TSB 56T-20 which addresses the kind of oil pressure problems people seem to be experiencing with the V-8 motor.

It calls for a revison on the oil pump and a new camshaft thrust plate.

Has anyone tried this method?

Thanks,
