Different casting number intake manifold. 67 & 68 same castings, 69 different .

Same as the 302 with casting numbers, they are different, but I don't think I can use a '67's. It's still all in the family.

Is the crank pin smaller on the 67 302, so does that make three different engines

# 610 intake can be used all 3 years.

67 302 is a small journal and 68/9 are large journals, so they are different but considered same engine family with same hp.
I guess the 67/8 are considered 295 HP.

Thank the person who did it, not who set the rules to race by.
