I think there may be a number of folk running 302 internals in their 289
blocks. The differences are very small as I understand. The note I
sent was because the reference item sent said that the 289 cold not be
bored to 302 conditions. I have a 289 5 bolt bell housing with a 30
over bore that I am considering turning into a 302 or better yet a 306.
I would use the crank, rods and pistons fromt eh race car to make that
happen.
