Rat vs. Mouse

How’s this for a budget idea: Build a cast crank 383 using a set of iron Vortec heads. But before you start building, know that GM Performance Parts now offers the HT 383 outfitted just like this with a mild hydraulic cam. This motor is rated at 415 lb-ft at 3,500 with 325 hp at 4,500. Bolt in the Hot hydraulic roller cam, and you’d have a thumper 383. The engine is PN 12497317, and it sells for $3,895 through Scoggin-Dickey or any GM Performance Parts dealer. View Related Article
