Can stock rod and stock crankshaft handle the power?

Try it and get back to us. There are plenty of guys running 11's and 10'a with 360 cast crank motors but I'm not sure if they are pushing an honest 500hp. Your best bet is to build the engine in the 350hp to 425hp with lower CR, then work on air flow, single plane intake,port heads it will probably run low 12'a when all sorted out in your somewhat heavy R/T, but the engine will be better suited to handle the 200 horse shot. Building a 500hp engine will need a much bigger cam, hi comp, probably race gas, and due to the hi comp when you hit the 200 shot the cyl psi will be off the charts
