if you are looking for the fireing order it is 15426378 i believe but you can also look behind the carburetor on the manifold. justtake off the air filter and it is right there just behind the carburetor... and i believe that the order is 15426378... that's all Ford V8 engines, except the 351, 400... which is 13726548. and the 272, 292, 312, and the 368 are 15486372... and all ford v8 engines are numbered 12345678. looking at the engine block from the front of the truck. 1,2,3,4 being on your left bank... and 5,6,7,8 being on your right bank.
the firing order for 1969 ford f100 240 six cylinder is 153624 i know this because i just rebuilt one.

It depends. Do you have a V8 or Straight 6? 1966 Ford F100 had several different radiators - some of which will fit, and some wont. If the 1966 radiation has a rear mounting flange, it will fit - assuming that both trucks have the same engine. Straight 6 and V8 engines have different rdiators
235/75/15 is the size on my 1966 f100
