A C1TE block should have the forged C1TE crankshaft and the best connecting rods Ford made (the C1TE rods are the same length as the ECZ 312 rods). We will see what turns out later on when I can get back down there this winter.
The steel crankshafts were reserved for the HD truck engines. The C1AE blocks simply replaced the B9AE-F blocks but the distinguishing feature of the C1AE blocks would be the reinforced main webbing versus the earlier blocks that did not have that. 1961 car and pickup engines would still have the EBU connecting rods. The C1AE blocks were a one year casting as they were replaced by the C2AE blocks which cast to the end of 1967.
