This was basically a standard rebuild on a 246 Dino engine. The only concessions to extra power were a special high performance valve job and higher compression pistons. The primary consideration was reliability and clean running. When we originally received this engine for rebuild, it had a bent rod. It was totally rebuilt with all new parts where necessary (bearings, gaskets, etc.). We ran it on our new Superflow Powermark dyno and saw a definite improvement over the standard rating of 195 HP (224 HP @ 7,200). The power improvement even surprised us and will make this Dino a very nice drive.
