Thanks, guys.
Ok, so let's talk about standard options first.
Hoggyrubber, yes, I'm looking for a 1/2-ton stepside shortbed, 1963-1966. And my main driving would be on a highway with speed limits between 45 and 55 and several stop-lights between here and work.
So, standard options:
1) V8 4 on the floor
2) V8 automatic
3) I6 4 on the floor
4) I6 3 on the tree
5) I6 automatic
Then I guess there are a couple different sizes of V8's and I6's.
I've always heard that a manual will get better mpg than an automatic, so I'd guess that neither of the automatics would be the winner here. I've heard that a 4-speed would be better than a 3-speed if the low gear was really usable, not the "3-speed with a granny" style, which I think is what the I6 4-speed would have been. So maybe the 3 on the tree vs. 4 on the floor would be a wash?
And a good 6-cyl should beat an 8? Would a smaller 6-cyl be more efficient than a bigger 6-cyl?
Am I putting too much thought into this?
