I doubt you issue is weak pressure plate springs. I suspect the fluid level is low in the fluid coupling or your clutch disk is worn out. I would look at those items first before you start looking at weak springs.

Deleted.....Info posted was for wrong year. sorry.

I still have my blue convt and the yellow convt is now in Ohio. I don't know if anyone has ever tried to compile a roster.

With the engine running, pull a vacuum line that runs directly to the intake and stick it into a bottle of water. Pull it out when the engine starts to die, so to keep it running. The water will clean out the carbon.

From Hollanders Interchange, all '51-'52 Chrysler 8 cylinder rear springs interchange except for the 8 passenger cars.

Documentation is the key to no deductions in an area like this. With the ink stamp you are part of the way there, now connect the dots.

Radials would be a deduction in both point judging and HPOF, but for your year car, up to four deductions are permitted for HPOF certification. Based on your comments and pictures, I think HPOF is the best place to register your car in an AACA National event. Documentation of rare features may be needed as well in the HPOF class. Hope to see you and your car at the Charlotte AACA National in April.

You can get your Judges Guidelines now and free by going to the AACA HOME PAGE and click on PUBLICATIONS. You can download it. This will be the 2017 manual, but for the information you are looking for, it will be accurate. By mid to late February the 2018 manual should be available to download. AACA has three distinct divisions for shows. CLASS JUDGING is point judging of cars. Most are restored, but there are a few original cars shown in this division. Original cars compete against restored cars with no distinction between the two for point deductions. HISTORIC PRESERVATION OF ORIGINAL FEATURES (HPOF) is evaluation and certification of unrestored vehicles. Deductions are made for areas where restoration is observed or disclosed by the owner. This division was established to promote the preservation of unrestored vehicles to be used as guides for individuals restoring their vehicles. DRIVER PARTICIPATION is for cars which may have some restoration done to the point they can not be considered as an HPOF car, but are not restored to the level to compete in Class Judging. This division also permits some modifications without deduction, such as radial tires on a car where they were never offered, a modern radio or aftermarket air conditioning. The Judges Guidelines will explain this in better detail. If you attend the Charlotte show, consider attending the Judges School on Friday at 2:00 in the Media Center at the Speedway.

My 1947 Roadmaster was built there. Original, unrestored, BCA Archival Award and AACA HPOF. 64,000 mile car.

Cadillac used a V-8 engine back to the early years, while Olds and Buick used straight eights. The Olds body was redesigned in '48 to accommodate the V-8 for 1949. Buick stayed with the straight 8 until 1953. It's been my understanding that the Buick "nail-head" V-8 was designed to fit in the straight 8 engine compartment.

CCStudent, why don't you consider joining AACA? Tell us where you are and we will connect you with a region.

Deleted, duplicate info

I agree with keiser31. It's a great combination with parts available. If you come across a 361 w 727 torqueflite, it's a great combination also. Same basic engine, just produced fewer years.

Thanks for your comments. The engine is coming from a Commander Starlight Coupe. I plan on keeping the manual with overdrive. As I get into the project, I sure I will have more questions. I do have the shop manual and will be reviewing it before the swap.

I have a 1951 Land Cruiser V-8, manual transmission with overdrive. The engine is stuck from sitting in a damp garage. Soaking the engine in various penetrating oils for several years has not free it. I have the chance to buy an engine from a 1954 Hawk, but it is an automatic. Is this a straight forward interchange or are there differences between the manual and automatic versions of this engine? Is the manual pressure plate a direct bolt up? What else should I look out for?

Keiser31 is right on this one. There are a very few changes from 1946 to 1947 and almost no changes from 1947 to very early 1949. Chrysler lumped all of these production numbers together as one run. These cars were mostly titled based on the year they were sold in. I would call it a 1948 because I think that was the highest production calendar year for these.

Since this is not a metallic paint, clean the area with a surface prep cleaner. (You can find this with the touch up paint at your local discount auto store.) Dab the paint into the area in a thin coat. You do not want to get a run. Let it dry and dab again (drying in between) until you have completely covered the area. Let it dry completely. Sand the area down with 1000 grit wet/dry paper, keeping the area and paper wet. Compound and buff this out and you should not be able to see it.

Are you running radial or bias ply tires?

If this is the same style power brake booster as a '57 Buick, look for a housing cover on the top of the booster with a screw in the middle of the top of it. Remove the cover and drip a few drops of transmission fluid in the opening. Pump the brakes and see it they start to return. This is covered in the Buick shop manual, so check the Pontiac manual as well. I was on the road to an AACA Meet and had to drip fluid from the transmission dip stick. I don't remember how many drops, but with pumping the brakes, it returned to normal quickly and we were back on the road. Thankfully we had a shop manual in the car to research.

It's a '65 from the parking lights wrapping around the front finder.

A car evaluated for a Repeat HPOF or Repeat Original HPOF award is evaluated to the same standard as the first time award. However the judges are primarily looking for modifications since the first award that would cause the car to no longer qualify for the award. In past shows, I've see HPOF cars that have had disc brakes added or the bias ply tires replaced by radials or hoses replaced and modern clamps used rather than the original style and the car loose enough points that it did not qualify for a repeat award. If there are enough modifications (or restoration) since the certification of the car, the HPOF team may recommend that the owner move the car to DPC or class judging for future meets.

Since you are in NC, take a look at Kaufman Trailer in the High Point, NC area. I have had one of their 18' open trailers for 8 years and it has been a great one. Ordered it the way I wanted it and it was a just a few weeks before it was ready for pickup. http://www.kaufmantrailers.com/

An HPOF vehicle can receive certification with a repaint. The number of deductions permitted increases with the age of the vehicle. A complete repaint is a significant deduction and if there are other deductions, it would be nearly impossible for a newer vehicle to be awarded an HPOF badge. The HPOF Original further limits the number of deductions, so it is very unlikely that a completely repainted vehicle would receive that award. Most HPOF judges can and do spot a repaint even if it is not disclosed by the owner. The disclosure by the owner on the evaluation sheet is only a guide to the judges. It does not limit deductions by the judges or mean a deduction will be made by the judges.

Everyone considering running radials on pre 1975 rims should review this article from SEMA. https://www.sema.org/files/attachments/WTC-2011-05-Bias-vs-Radial-Tire-Wheel-Fitment.pdf

There is a vast difference between digitally converting a color digital photo and a photo shot with B&W film. Notice how the sky turned black in your B&W photo and the red and green on you car would show as different colors of grey.
