I'm speaking about performance and capacity specs. I've read several different HP ratings that may or may not be describing the engine or drawbar rating. If someone knows more details(torque etc) besides what I've listed below or can correct this info - please do. I'll dig out my manuals tonight and see what I find there.... 30 H.P., "Flat-Head" 4 cylinder engine 4-speed transmission 2400 lbs Dry 540 RPM PTO System Ferguson System 3 Point Hitch Position Control and Automatic draft control Produced from 1947-1952 at Dearborn, Michigan [Reply]   [No Email]

Problem with the flatheads is the large combustion chamber , so getting 7.0:1 would be about the best you could get with a normal carb , then you would only get another pony or two . Raising the rpm to 3k would get you about 10 more ponies . Higher octane would not come into play until your compression ratio exceeded about 9 to 1 . [Reply]  [No Email]

Someone will correct me if that's not right. My memory is far from perfect. :) [Reply]  [No Email]
