1976 308 GTB Dry Sump

This dry-sump 308 GTB engine was rebuilt with an eye towards improving the performance with additional horsepower and torque. The customer specified Ferrari P6 camshafts paired with a higher compression ratio. Based on the dyno results, this is a combination that works very well. The additional power made a difference on the road, the rebuilt engine developing a nice power curve that made the Ferrari faster and more fun to drive.
