Definite possibility that've I've been considering. I've previously considered cannibalizing parts off engine #1 for engine #2, but then I end up with a partial engine setting useless in the shop. Only upside is I have a spare in case I blow up #2 or don't like the higher horsepower mannerisms. I'd like to have a complete engine that I could possibly sell if I'm not going to be using it. Still like to hear from people that have run the stock rockers in a similar setup. I ran the 280/474 Purple cam in a 440 with stock rockers and had zero issues. That's my own personal experience, though.
