Mal,
Failed again, if you PM me I will try replying with photos, I need you full e-mail address so I can reply by G mail.
Photo management on the computer is not my thing!

Mal,
I haven't replied earlier because the site was down.
There is a cavity in the front of the block that receives the water pump. Water enters the pump from the side of the block , through a slot into the back of the pump. The "baffle" I referred to is the part of the block that forms the back of the cavity. I have an old block that I photographed to show this cavity so you can compare it with yours.
The water from the pump passes though another slot on the side of the block and enters the water distribution plate that directs it along the side of the block to the outlets adjacent to each cylinder.
I am still having difficulty understanding how you could adapt the external pump to this location, unless you are simply relocating it to the front of the block but leaving it external.
The only way I could envisage a front mounted pump arrangement is with an original front mounted pump, something I would want to avoid!
As to the other point about when these pumps were introduced, I had understood the side pump came first but I can't recall the source of that information however I just checked the engine number on the car that I know of with a side pump and its engine number is lower than both of my cars with front pumps.
Also, to remove the fan belt it is necessary to remove the radiator but that is not because of the water pump, its to clear the harmonic balancer.
The Standard Eight was fitted into the engine bay for a 6 cylinder and it is a very tight fit, back and front.
My attempt to attach the photos failed, I will try a PM

Glen,
The red Packard in the photo is a 1921/22 Single Six model 116. I believe if you measure the wheelbase it will be 116". Engine/chassis numbers would confirm the model.
My car is a 1922/3 Single Six model 126 and there are differences that I am not familiar with. My distributor has single points if yours has dual points then it seems that is one of the differences.
I would modify the distributor to take single modern points. I have done this with my 1929 Packard and its not particularly difficult. You need to make a new base for the points then find a set of readily available modern points and mount them on the plate so that they operate with the cam. Once mounted you need to rotate the plate to the location to give the correct ignition timing using a static timing light then drill it and screw it in place. A bit of fiddling around but worth the effort.
BTW there is a parts list for you car on this web site under "Packard Literature and Manuals"

Glen,
The spark plug on your Fuelizer was provided to heat the fuel to assist in vaporising it. It is unnecessary with modern volatile fuels and would actually be detrimental leading to vapor lock.
I have a 1922 126 and have an old original coil, it has 2 sets of secondary windings. One set for the engine spark plugs and another for the Fuelizer plug. I have replaced this with a new Bosch 6v coil and leave the wire from the Fuelizer leading out of site just for "show".

Mal,
I have two 1929 6th Series Standard eights both with front mounted water pumps. I have only seen the side mounted units and have no experience with them but I cannot see how you could adapt the side mounted pump into the front mounted location assuming that location on your engine is made for a front mounted pump like mine. Your comment " and can see that the water pump body will actually fit into the housing on the front of the motor " suggests that your block has a blanked off opening for a front mounted pump. As I recall it the side mounted pump is a completely different pump, it has a conventional external gland nut for the seal whereas the front mounted pump has a gland nut "internal" out of sight that is adjusted with a small rod inserted through a slot ( usually takes a few attempts to achieve the desired result).
The belt tension is achieved by rotating the pump, which is eccentric to the opening, in the block.
I am not sure I understand your question about the baffle, on my cars there is a baffle that is an integral part of the block behind the pump, if your car has the opening for the front mounted pump then you would expect that it would also have the baffle.
I regard the front mounted water pump on the '29 Standard eights as their worst feature I have often wished my cars had side mounted pumps that are easily adjusted or removed.

I was once told by a paint expert that there is no need to use a "engine enamel" unless the engine will be started very soon after painting. Engine enamel simply cures more quickly. Providing the normal enamel has time to cure, say a week, before the car is started then it is fine. So if this time period is OK you have a much wider selection of colours.

Packard V8, the adapters are made from steel.

Packard V8,
I am sure Updraft, who raised the question will be pleased top know the source of correct plugs.
Strangely I can't recall anyone commenting on the fact that I have modern plugs with adpaters, unless you look closely they look the same as the 7/8" plugs so I will stay with them.
I don't know what the correct 7/8" plugs cost but I am sure they are more expensive than my 14mm ones. Still I would prefer to get the correct ones.
The internet and e-bay have made most things available regardless of where we live, This forum is an excellent source of information, like for example OD's posting of the Autolite site and the one you posted.
Most of the parts I needed for my projects had to be found before the internet , in my case I had a huge "wish list" and I found most of them on 2 trips to Hershey . Since then most of them have come up on e-bay.
I would like to raise something to argue about but can't think of anything off hand!

Good question OD, I bought them at a local swap meet many years ago before we had the internet and I while I suspected that the correct plugs were probably available in US I assumed they would be very expensive and I was, at the time buying for 3 project cars (now all finished), 2 x 8 and 1 x 6, a total of 22 plugs. The adapters were inexpensive and I could then purchase the modern plugs easily and cheaply including future replacements. I obtained advice from the spark plug agent about the best plug at the time.
Today I would buy the correct plugs off the internet

Sorry if I confused the issue, There are adapters available that screw into the standard 7/8" spark plug hole that allow the use of modern plugs. I have them on my 126 & 633.
