Ferrari 308 GT4 high performance engine overhaul

Model: 1978 Ferrari 308 GT4

Project Overview: This GT4 was purchased by our customer in need of a restoration. Carobu was enlisted to rebuild the car mechanically. The V8 engine was rebuilt into one of our larger displacement 3.5-liter motors while retaining the original Weber 40 DCN downdraught carburetors. The handling of the Ferrari was improved with the addition of a Razzo Rosso Koni coil-over conversion. Euro 308 Quattrovalvole 16-inch wheels were also installed. This car was featured in Forza Magazine after its completion.

Engine Specs:

279.73-hp @6600-rpm and 240.91 lb-ft of torque @5300-rpm
