Looking to buy/build 500-600 fwhp 360

So, the stroker short block rotating assembly isn't recommended for nitrous. I don't think hughes engines has time to assemble an engine. That really leaves us with Eagle Motorsports in Eldora, IA. Which, btw, sounded like they could tackle the project. Now I have to decide if I sell my running 360 and find a rebuildable block, or just ship them my engine, they are not too far out on their builds.
IMO ship them what you have.
You know what you are starting with, rather some junk yard piece.
