The ’58 Chrysler 392 Hemi is bored .040 over and topped with 1956 Chrysler Hemi heads. Arias forged pistons travel north and south in the cylinders with Howards aluminum connecting rods hooked to the Moldex crankshaft. A Chet Herbert roller camshaft does the thumping, while a Littlefield-prepped 6-71 GMC blower forces excess fresh air down the Hemi’s throat. Jay Taylor performed all of the machine work on the block and cleaned up the heads, while Henry Velasco dialed in the crankshaft. Roger McMartin designed the ground-pounding mill and Terry screwed it together. Donnie Johansen performed the degree work on the camshaft.
