Piet List; This is for anyone interested in adapting a Model T water pump to aModel A block. I have a note here for John McNarry and one other fellathat made mention of it. John, the T pump does indeed bolt right ontothe A block. It uses the same gasket too. (Henry's Interchange System?).It does interfere with the oil filler tube......... I have a choice of using the above or a side mounted washing machinepump because the radiator I had built for my Scout is too deep (front toback). That is because I had the radiator built big enough to handle 30%more capacity than a stock "A" radiator. I did that because I intend toinstall a stock looking but "souped up" A or B engine down the road,hence the need for more radiator area early on and about the onlyconsistant problem with Model "A"'s seems to be overheating when used inaeroplanes. I am told that by numerous old Ford Gents. It has to do withthe position of the stock water pump being up where it is on top of thehead when in the car and the cruising RPM being "high" when used in aplane. Can anyone tell me what the "cruising" RPM is in a stock "A" autoat 55 mph highway speed? I choose the "T" pump instead of the washing machine deal solelybecause it looks better. It can be hid under the cowling so the cowlingfit on that side is much cleaner and simpler. It bolts onto the block inthe normal spot and induces the liquid stuff into the side of the blockavoiding "steam cavation" of the pump in the stock location. The samealuminum plate that becomes the "rear" engine cover plate is extendedout a bit to hold the other end of the tube shaped "T" water pump. This"steam cavation" issue seems logical to me and I thought I read of itfrom someone on this list, no? I also heard of it from the S.O.S.S.racing gang as well. That Magazine is where I saw this "improved" aftermarket tubular racing "T" pump advertised. I also have pictures of aScout (Broadhead?) with a "stock" "T" pump on the side as well. Seems tome that is what got my attention to start with. Chad Wille (St. Croix propellor maker) built a georgeous Scout poweredwith a Model "C" (his designation) and used NO water pump at all, justthe thermo-sypthon "system". Sorry Chad, I don't trust that one! Hereports in the 40 some hours he flew it prior to it going into a Museum, it never had a hot water problem................ The Model "C" issuealways starts a fight......Chad's came from an original outdoor standalone power unit used in mining, I think? He hales from Oregon, nowlives in Iowa, flies a Piet he built 25 years ago, makes props and Pietkits and has built 3 of them, I think. John, the engine man, McNarry, ever heard of this Ford Model "C"contraversy? I have had a few people say they existed but Grant Maclarenand the A gang's research says no, that came from a "C" casted into thehead of a "B" engine. Chad's "C" had a few differences too such asautomatic distributor advance and so on.........Earl MyersPiet List; This is for anyone interestedin adaptinga Model T water pump to a Model A block.
