I'm in the research phase of building a 930 into a farm stock. My plans are to build a 504 from a 2390 or 2590 and put that in place of the 377 gas. Our rules state we have to run the stock style injection pump and a turbo with a 2.3" inducer bore. RPM limit is 2750. I have talked to a few case pullers but I'm looking to collect as much info and advice as I can before I start my build. I have not purchased any parts as of yet and I would like to have my plan complete before I start buying things. I have been told there is a gentleman by the name a Carl Conn in Wisconsin that is an excellent resource, does anyone know how to reach him? Any and all advice and experience is greatly appreciated.
