Engines were completely dissembled, cleaned, checked, and freshened less than 75hrs ago. At that time new Dart CNC heads and all new valve train was installed. All hours were very easy hours on a small lake, fresh water use only. Engines were recently removed from the boat and had a leak down test performed. All cylinders were 76-78 out of 80, filters were cut open and no sign of any metal was present. Engines ran fantastic at all times with zero issues. Sold as-is. Asking $8500 each. Will consider selling short blocks also.

Pics sent. I am located in Idaho. Yes the motors were set up for blowers. I was running b&m 420s one them at about 4-5 lbs of boost. Ran great and very reliable. I am guessing compression with the dart heads to be a little under 9:1.
