Ferrari 275 GTB/4

308 GTB 3.5L Engine On Dyno

This slightly warmed over 275 GTB 4 cam engine was built by another shop previously and had a fair number of miles on
it. The exhaust headers had been modified with slightly longer stainless steel primary pipes of 2mm larger
diameter. Special SS merge collectors were used and the “boxes” were eliminated. This was done to help reduce the heat felt in the car floor during long trips.
