[68Gold/white]

Both engines are marginal cubic inch wise, for a pickup, my opinion. 327 would be smalles engine I'd every use. It just takes a goodly amount of torque to push a heavy pickup around. Needs to be 350 or larger. Yes, that's 67. I'm thinking now tough.
Yes less cubes will work....it's still a free country. I admire folks with 6 bangers, just like the olden days, cool!
