If you’ve been sitting on the fence whether now is the time to strike on that dream engine build for your Mopar, let this be your sign. Callies Performance Products not only extended its October sale on all cast iron Gen II (426) Hemi and Wedge/RB440 engine blocks, Compstar Big Block Mopar Crankshafts and Compstar H-Beam connecting rods but now they’ve included their entire selection of Gen III 6.2L and 6.4L Hemi blocks, cranks and rods.

Running the entire month of November, Callies has reduced prices on all Mopar products in their catalog. Whether its a Gen II or Gen III Hemi block (both are officially licensed products by Mopar and carry all legal emblems and part numbers) that you’re looking for, or needing some killer Compstar H-beam rods or a Compstar 8 CWT Hemi crankshaft, Callies has them in stock and ready to ship. Just take a look at the flyers below.

More importantly, because Callies is a licensed partner with Mopar/Direct Connection, Callies also can outfit you with complete Gen III Hemi cylinder heads, rockers and a whole bevy of other components – whether it’s a stock-style replacement 5.7L or a wild Redeye or Demon 170 rebuild. Like we’ve said before, there hasn’t been a better time to want to build big horsepower than today. Check out Callies’ catalog today!
