CHRYLSER BIG BLOCK WEDGE & HEMI: As perennial contestants in Mopar Muscle's Engine Challenge, we've demonstrated combinations setting industry standards. Our big block Chrysler builds start with the unusual 500hp 383 and range up to aluminum blown Hemi's. Fed up with the cheap Indy crate engines? Try one of our Hemi's with legendary Stage V cylinder heads. It's the blue-printing and ported head/cam combinations that make these engines a great value!
