I bought a new Ram 1500 with a 360 magnum back in 1994. Had 230 hp. 318 magnum had 220 hp. Took it to the drag strip during a Mopar meet, ran half a second quicker in the quarter than an otherwise identical Ram with a 318 (as I recall, 17 flat vs. 16.50 or thereabouts). We talked about it; he thought they should have been closer since I only had a ten hp advantage. My response was, yeah, only ten more peak hp, but the extra 42 inches gives me a stronger low and mid range.
The difference in cubes between a 318 and 360 is exactly the same as the difference between a 360 and a 402 stroker. All other things being equal, which is gonna make more power - the big motor or the smaller one??
