Interestingly these bolt holes were still drilled and tapped on all other American built flatheads. The front motor mounts bolted to brackets on either side of the timing cover. The vertical drain petcocks and a bulge in the pan rail for a freeze plug can be seen in the following picture: The block featured drain petcocks pointed straight down at the front. The oil pan rail had four freeze plugs, two per side. There was no provision for crankcase ventilation. The main bearings were 1.998 to 1.999 inches and the rod bearings were 1.998 to 1.999 inches. The 1932 V8 engines features a 3 1/16 bore by a 3 Вѕ stroke for 221 cubic inches. These features can be seen in this picture of 18-1:ДЄnd on this picture of a very early production engine:Д®arly in production the oil dip stick was relocated to the oil pan and the block castings were changed to locate the steady rods in the bell housing casting. The very early 32 motors feature some unique features, such as bolt on steady rod brackets and a block mounted dip stick. This engine was actually prototype motor number 243, but they had to start somewhere. And so, if you visit the Henry Ford Museum you can see production V8 number 1, 18-1 itself. Maybe Dave Cole or David Rehor know all of the changes made in 1932, but I sure donвЂ™t. A proper discussion of 1932 Ford V8 motors would include as many pictures, or more, as I have in this history discussion. The number of production changes to engine design in 1932 was phenomenal. And so, into the turbulent under developed world of prototype motors, the V8 Ford was introduced. Ford Motor Company knew the first V8s were so bad that the first 1500 were not allowed to be sold to the public, they were for static display only and were supposed to be returned to Ford for engine swaps before being sold. Apparently as Henry walked past the newly started production line turning out the shiny new 1932 4 cylinder Fords he made the decision to shut the line down and introduce the V8! Ford dealers were without cars for months. Henry gave the order to start production of the improved 4 cylinder car for 1932, the model B. Henry had a crash program going to develop an 8 cylinder motor, but it was not developed enough to put in production. In the beginning of this story it is 1931 and Chevrolet has a 6 cylinder car. Here is the 221-239-255 cube flathead block story with pictures, to the best of my knowledge and ability to collect pictures so far. 1954 вЂ“ Canadians and others used 8BA for last year, no USA flatheads.1952 вЂ“ 8BA sometime around here the exhaust valve seats were eliminated.1950 вЂ“ 8BA sometime around here the intake valve seats were eliminated.1949 вЂ“ 8BA: removable bell housing, changed water passages.
