Ok, the intake was already off the engine. Here are all the numbers that are on the top of the block in the valley where the intake bolts over it.
In order from the front of the engine going to the back . . . .
large number 26
small number 9c30
large number 117
circular number pattern of 35791 (NOTE) the 1 may actually be a line, I can not tell. The small line in the middle of the circle seems to point to the number 5 in the circular number pattern.
Bruce please help.
Also, the distance between the front most intake bolt hole in the head to the same one on the other head seems to be exactly 9.5". Someone else in the forum mentioned that 9.5" is a 351w and 7.5" is a 302, is this true?
