My recipe... N/A Coyote 5.0 with 500+ HP (forged internals for STRENGTH ), gears (4:10's?), revised suspension front and rear, maintain 75% tow/haul rating and let it rip!
IMHO
stock coyote already has a forged crank and rods have been forged since the gen 2 motor. The pistons however are still hypereutectic, however these motors have reliably handled forced induction in the 700-800 range, guys have pushed them further, but generally on borrowed time past that. 500+ NA and the stock motor will live forever.
