Looking for info on pricing a engine. The engine is from a '07 RXP with 27 hours and currently has the Riva valve spring upgrade kit and Riva/ARP head sutds installed. At the end of last season, I pulled the head for a valve job and oil seals. Engine has not been started since then and will not include exhaust, intake manifold or supercharger.

I searched and did not locate much on recent sales of engines in the with or without the head.

Thanks !
