Wire Wheel Covers

#11

Home away from home

Would someone please educate me on what was offered in the way of wire wheel covers (vs wire rims) on the '55-'56 senior cars. Were they an available option? Rarity? Have they ever been reproduced?

On it's way to Arthur Gould. Thanks.

Terrill Machine Shop in DeLeon, TX is another who has done decent work in rebuilding pumps for a long time but I don't know their current status and they don't have a website.

Re: 356 CI Compression Ratio

#13

Home away from home

Some people do it to raise compression too. My Custom had a distinctive racing stripe when I bought it that had been applied by someone sometime prior to the early 60's. Maybe the head was planed, but the 327 head still had a slightly smaller combustion chamber so I used it. I did use the copper spray sealant.

A warped or bent head should pull down flat quite easily and even very slight imperfections will be sealed when using a proper head gasket and Copper-Coat or some other similar sealant. Planing should be done only in extreme cases.

Water Pump Rebuilds

#14

Home away from home

Any current recommendations on getting a water pump rebuilt? I have a spare that is bad and I'd like to get it redone so I have one on hand.

I've little doubt the heat riser valve has been stuck in the past. If my suspicion that the original head has been planed based on the volume measurements that would support a story that the head gasket failed and was replaced sometime in the past -- perhaps the head was found to be warped or eroded. The valve lifters are hydraulic on the 356.
BTW, I did measure the 327 head prior to installation with machinists straightedge and feeler gauge, measuring up to 3 thou in the center from the ends, which is the limit.

I'd guess that at some time or other, the head gasket on that cylinder leaked, or the engine got water in that cylinder from some other cause. Chronic detonation can cause erosion of metal surfaces, but this would usually show up in damage to the piston.
An intake manifold leak can lead to burned valves in specific cylinders due to running too lean. A problem with the water distribution tube in the block could lead to valve problems in a particular cylinder, and so could improper valve adjustment or a a stuck manifold heat valve.

I believe the 356 is the largest displacement engine this HC head will fit.

Heads with larger combustion chamber volume are probably for higher displacement engines. As I understand it, a number of Packard heads will interchange among different displacement engines.

Re: 356 CI Compression Ratio

I pulled the 356 head and did some comparative volume measurements of the combustion chambers. The 356 measures 95cc, the 327 head is 90cc, and the HC head is 120cc. Very little difference between the 356 and 327. Why the supposedly HC head is so huge is a mystery. With that head I think the compression would be too low for the gasoline to even combust -- the engine would not start. The plan is to install the 327 head but with such a small difference I'm tempted to check volume on a 288 head to see how it compares. I'm wondering if the 356 head has already been planed at some point in it's life. If one does the math assuming the 356 head is stock, there's a 5% difference in volume so a CR of 6.85 would become 7.21, not the 7.53 per the chart.

However, as it seems whenever something is torn into other issues arise and this time is no different. Head removal revealed a problem with cylinder #4. The rest all look just fine and the head gasket appeared fine with no indication of leakage anywhere. There is oddly some severe metal erosion on the intake valve head and on the block between the cylinder bore and exhaust valve. Picture attached. The seat on the intake looks okay still, but the seat on the exhaust looks compromised -- not severely but I assume there's some leakage.

Any ideas how this could happen on just #4?

That seal is actually meant to be installed in a groove in the decorative snorkel cover. You could probably make one from some heavy felt and glue it in. The majority of cars I get in no long have one and it makes no difference.

I don't think that's the case for the '55. Here is the underside of the cover. The bottom lip rests on the rubber seal. If the seal is not there it can only rest on the metal lip of the filter.
