You have the makings of a great combination there. Eagle makes a 4.25 Stroke crankshaft that will go right in that Gen 6 block. You'll have yourself 540 CID. Eagle also makes complete Crankshaft Reciprocating Assemblie that will include a forged crankshaft, H-Beam rods, and either high or low compression pistons. I'd also slide in a mild streetable solid Roller camshaft too (NOT a hydraulic roller!) and you will have one bad-ass motor that will have very little or no equal to whatever pulls alongside you!
