Honestly I like posting in this section of Moparts the most because of the experience, knowledge and honesty of the replies. The unfortunate part for me is I have not needed to come in here since building the ‘95 5.9 about six years ago. Back then this section was a very instrumental in helping me on my first solo build. I used Hughes Engines for all the parts and technical guidance and the engine turned out just as I wanted. The current 5.9 is a full roller motor with iron Indy X heads. It winds up quick and made 275 hp/316 lb ft at the rear wheels with a 625 Carter (since replaced with a Quick Fuel). With a full interior, 44RE trans, stock suspension and with 3.55 gears it turned its best time at the Nats two years ago of 13.92 @ 97 mph. It ran out of air at the top end.
Recently I had Hughes quote a stroker kit and heads for the 5.9 but as said by dogdays I need to make sure that it would satisfy. I also had Brewers quote a four speed four it for added fun.
I’ve had a strong 383 and a stock 413 but never raw 440 torque.
