Actually there is lots of Gen lll hemi blocks available as I checked because I ordered one. Mopar block is actually discontinued.Also the mds is always delectable as it’s a matter of installing plugs and lifters.Yes I’m waiting to see the dart production but I’m in doubt it will happen
GEN III HEMI BLOCK SET TO ‘CHANGE THE GAME’
Currently there are no Gen III Hemi engine block options in the aftermarket besides the Mopar Performance offering. But Dart Machinery of Warren, Michigan, has a fresh design with poured prototypes and a dedicated machining program underway. As of early spring, the company was just waiting on additional castings to complete its validation program.
“This block will change the game,” promised Mike Sanders. “We’ve added extra cooling capacity and changed the oiling system.”
The new block will not allow MDS (cylinder deactivation) but will be available with or without provisions for variable valve timing (VVT). It also comes with steel four-bolt mains in all five locations and will be available in either a 9.250- or 9.285-inch deck. Maximum bore will be 4.250-inch.
“Now you can build nearly a 500-cubic-inch Gen III Hemi,” Sanders noted. —Mike Magda
