The Lord of Chop is back in action on his Squarebody K5 GMC Jimmy build and things are getting serious. How serious you ask? Try 572 cubic inches of Big Block Chevy power, serious. The best part is, we're gonna show you the entire engine build process. In this episode, Zac preps the old 454 to come out while engine builder, Jacob Villemain goes over the Dart Big M engine block, the block machining process, and balances the custom stroker crankshaft for Zac's 572".
