How would you build a 416 Stroker 340?

I think you can actually piece together a budget 416 rotating assembly for a little under what they want from mancini. I've seen cast eagle cranks for about 300$ a set of SIR rods for under $300...then those darn pistons...Diamond has 4.070 forged units for 567$ at hughes or KB stepped dishes for 52$ a piece..hmmm 8 x 52 = 416....weird. through in a set of rings rod bearing and main bearings and you might come in at or around 1200$ bucks. around here you can get a rotating assembly balanced for 125$, block clearancing you can do yourself. leaves little left over for head work if you've got 2000$ laying around
