Compatible with the Hellcrate wire harness for pre-1976 swaps and custom builds, part number DSR1500-DC is designed for E85 rather than good ol’ gasoline. Fitted with 1,700-cc injectors and 356 ported aluminum cylinder heads, the 7.0-liter monster belts out 1,000 pound-foot (1,356 Nm), enough to make a heavy-duty turbo diesel truck blush.
Boasting a 4.100-inch bore and 4.050-inch stroke, this 426-ci leviathan features a stroked BGE cast-iron block with four-bolt main caps, ultra billet steel for the crankshaft, ultra I-beam connecting rods, and billet aluminum pistons. The force-fed lump further sweetens the deal with a high-performance valvetrain, a high-performance cam, and billet aluminum covers powder coated in black. To whom it may concern, the non-E.O. engine kit that includes the Hellcrate wiring harness is $2,265.
Designed for a seamless swap in any 392 supercharged vehicle, the force-fed mill is lubricated with 5W-40 synthetic oil. The supercharger comes in the guise of a 3.0-liter Whipple Gen 5, and the throttle body is a 112-millimeter unit supplied by Whipple. Because of the blower, the 1500 HEMI runs a 9.7:1 compression ratio. The 426-ci stroked BGE 392 block features the same bolt pattern and motor mounts as the Hellcat V8.
Direct Connection lists the 1500 HEMI with a tentative install time of 40 hours. It also mentions that 1500 HEMI-swapped vehicles manufactured for model year 1976 and later cannot be driven on public roads or highways.
