This Porsche Type 616/12 flat-four engine was originally produced for a 1963 Porsche 356B 1600S and was rebuilt to 1,883 cc with Nickies cylinders, forged 90mm JE pistons, and a 912-sourced crankshaft. It was recently run on a stand at Redline Service, where carburetors were adjusted and timing was set. The engine features dual Solex 40 PII-4 carburetors, a 12-volt Bosch generator, and an overhauled Bosch 022 distributor.
