I can agree with that.

not bashing btw, sometimes I'm a lil more blunt for the other readers sake in my responses, so as the idea does not get lost.

Ive found motors and just couldn't be tuned........ even stock ones, good compression, clean burning, just........ wouldn't get good MPG, hell, my 95 1500 with a 318 and 3.55's wouldn't get 15 to save its ***.

It got 10 before the R/T cam, and HP compooter.
