tri5, That '54 450 should have a 302 in it, unless it's been changed, & not a 248. 1954 was the first year that the wipers were above the windshield on AD/ND trucks, but only on 400 series, and larger trucks. You'll also notice that from 400 series up, the 54 models used the round park lights, & not the square park lights as the 350 series down use.
