If I was starting from scratch, hands down a junkyard magnum 5.2/5.9 with a supercharger or turbocharger. 500+hp for pennies on the dollar compared to a comparable n/a SB or BB.
You know I gave this serious consideration - and may give it more consideration - but what initially scared me away from a turbo is the potential for turbo leaks in the piping and how in general more complexity = more problems.
That said, with 5-10psi boost on a 5.9 Magnum, even without an intercooler, that should be a 550hp motor.
I can't see a supercharger kit being cheaper than building a N/A big block though... I could be wrong of course.
