OEM 340/360 rod in a 408 stroker...??

Oh my old 340 saw 8000 RPM and 8500 in the water many many nights with the stock rods, polished beams, floating pins, weight matched with ARP bolts, never a problem there either.

I have a set of H beam Eagle rods laying around that I'll use for the stroker, mainly just because I have them, but I don't really think I'll need them at 600 +/- HP.
