Yes.

"Though the Power Pak 273 used the same block, main caps, forged crankshaft, forged rods, cylinder heads, 1.78/1.50 inch (I/E) valves, adjustable rocker arms, exhaust manifolds, and oil pan as its plain vanilla two-barrel sibling, Chrysler upgraded everything else. With its 480-cfm Carter AFB four-barrel, domed, 10.5:1 pistons, hotter 0.428-inch-lift solid cam, chromed 10-inch air filter, dual point distributor, and free-flowing single exhaust system, the Power Pak goodies bumped the two-barrel mill's 180 horses at 4,200 rpm and 260 lb-ft at 1,600 rpm to a much more exciting 235 hp at 5,200 rpm and 280 lb-ft at 4,000 rpm."

I’ve recently watched the YT documentary on Herb McCandless and he talks about shifting the 440 cars at 5000 RPM while other drivers were needlessly spinning them up to 6000. Guess who won Class? BTW, to anyone that hasn’t taken the time to watch the Herb McCandless doc, you are denying yourself of something awesome!
