engine and trans identification
my son has a 77 ford f100 and believes it has a 302 with a c4 auto trannie. where would the engine # be and what indicates the type of engine,302,351,etc. also the trannie I understand is identified by a square pan,correct?.are all c4 the same od dimensions and the yoke input the same from what year to what year. Is there a ford link where information as per the vin #,engine etc. available Thanks, Chris

If the motor is origional check the valve covers. 302's have 6 bolts and 351 Modified's have 8 bolts. 351 Windsor's were not origional equipment for '77 trucks. If the motor has been changed from a 302 to a 351 Windsor, the valve covers will have 6 bolts same as the 302 so you'll have to check the firing order to ID the motor. The firing order is stamped on the centerdome in front of the carb. The 302 firing order is: 1 5 4 2 6 3 7 8, the Windsor has the same vlave covers but the firing order is different (1 3 7 2 6 5 4 8). There are other differences as well but this is the easiest way to ID them.
