approx 75K miles, all original and complete from oil bath air cleaner to oil pan. Runs but now disconnected and will be removed from the Merc soon or when sold. Not much more to say about it other than it's all there... 8BA style Edelbrock heads, powder coated black with polished fins. One head has some amateur polish work done on the combustion chambers. Needs to have final clean up done on it. No actual miles on them, was only used on engine start up stand. $450 Shipping on the engine runs about $175 through Fastenal. I also have the '53 Merc-o-matic trans if someone wants it, make offer... Thanks!
