The People-200/250ci distributors and canister heads will match an Australian 200/221/250ci Pre-Crossflow, ánd vice versa. As a result the oil pumps are usually not interchangeable. Consequently exhaust headers created for an Australian 250ci actually will not really fit the US-250ci, or vice versa.Īnother example would end up being the oil water pump, while the oil pump get is the same dimension, the bolt styles are various. For example, all US-250ci motors got a reduced mount starter, while the Australian and Argentina 250's got a high mount beginner. Some of these differences are usually the exact same as their Us all counterparts, while numerous are not really. In this content we'll cover a bulk of the differences, for motors produced in the USA, even though you just require to understand three to recognize the engine sizeWhile Australian and/or Argentina built motors are related to their Us all counterparts, they possess their own unique collection of distinctions. To the unskilled enthusiast all little sixes look identical, however there are minor distinctions which can end up being easily seen if you understand what to look for. mount, iron headsĬarburetor mount 19: Part II will follow.Ever wonder what dimension engine you possess? If therefore, your not the only one. If there are three studs, it's for a Stromberg carburetor 1934 and up (see picture below article).ġ932 models have iron heads, 1933 models have aluminium heads, giving the 10 HP more power. If there are two studs, it's a 1932 or 1933 intake manifold for a Detroit Lubricator carburetor. If the intake manifold is present, look at the studs the carburetor is mounted. 19 models have the waterpumps mounted to the engine body. The early engines from 1932 to 1936 had Waterpumps mounted to the cylinderheads with the water outlet on the pump. Let's take a look at the 21 stud Flatheads. Let's expand the above table: studsĢ1 stud Flathead from 1933 Differences in construction details can be seen even if you have a smal photo. If the bore is somewhere between 3.0625 and 3.1875 inch, it must be a 221 cui Flathead. The bore can be 2.6000, 3.0625, 3.1875 or 3.5000 inch, but these values can varies when the cylinder is bored for oversize pistons or cylinder sleeves. The different displacement of the 24 stud engines can be determined by these two values. The bore is the diameter of a cylinder and the stroke is the way a piston goes up and down. If possible, measure the bore and stroke. If you count 24.you can have anything else and we need to look closer.
These Flatheads were build for big Ford trucks (F7, F8) or Lincolns. If your count is 27 you have a real monster. The early engines have 65 or 75 HP, all later engines have 85 HP and 221 cui. If the count is 17, you have the smallest of all flatheads, the 60 HP and 136 cui flathead that was build from 1937 to 1940. Ford has build several cylinderheads, but only 4 different heads in count of the head nuts: 17, 21, 24 and 27. If someone is talking about a 24-stud, he means an engine with 24 head nuts (or 24 studs in the block). One simple characteristic of a Ford Flathead is the number of head nuts per cylinder.
