This engine was in an Adams Aero formula Vee - used for autocross and hill climbs. I was told that it was balanced and blue printed. It has a starter, headers, and four POSA flat slide Carb/injectors with cool velocity stacks. It has an adapter plate for VW tran, so will fit Porsche 914, sand buggy or one bad micro bus. The header is for mid-engine mount. The engine would make a great spare for a B510 or 210 racer.
The engine seemed sound when we yanked it, but who puts a Datsun in a Vee?
