We went through all the numbers a few months ago on this combo & I think the 1972 175 hp/350 engine got the better head & an optional higher lift cam. It also had some alt. choice about the pistons too. Sorry I didn't bother to look, just typing from memory. It seems like it did carry a little more weight, but the heads cam & compression made up for it.

Edit: I got to thinking about it & I couldn't resist looking it up
The 175 hp 1973 now (as of 7-07) carries 283 factored HP. The 1972 175 HP carries 270 factored HP.
