1978 F100 400M C6 2wd

Hello, I am located in Huntsville Al, and I am always looking to learn and improve my old F100. Carl

Carl - Welcome to the Bullnose Forum.  

While we specialize in the Bullnose trucks, meaning 1980 - 86 versions, we do know a bit about the earlier ones.  For instance, I have a friend that comes over frequently with his '78 F150 w/a 351M, which is the little brother to your 400.  We've done quite a bit of work on it, so I do have some experience with them.

Speaking of the 351M, it is part of the 335 Series of Ford's engines, and that is my favorite series.  The engines are lighter than a 460, but the 400 has slightly more stroke than the 460 so puts out considerable torque.  In fact, the 400 for Dad's truck puts out 500 ft-lbs at a relatively low RPM, which is perfect for a truck.  And, those engines are "underdogs".  But, in the right hands they can really shine.

Welcome, Carl, from a neighbor [70 miles west of you].
