way too heavy. Cast iron everything! These newer motor were all cast aluminum with integrated water and oil pumps, serpentine drive, MPFI, yadda yadda. They couldn't save the Slant either, too small valves too long of a stroke. Bring it back in Aluminum with a redesigned cross flow head, EFI? Its still a straight 6, long and long for all the new transverse mounted platforms. Sometimes you gotta start fresh. Spitfire motor, over 300HP in a NA V6? Try that in a 5.2 with 2 less cylinders and a wonky balance crank.
