The 330 GTS evolved into the Ferrari 365 GTS in 1968 with the engine increasing from 4.0 liters and 300 horsepower to 4.4 liters and 320 horsepower. Just like its coupé sibling, the 365 GTC, the GTS was powered by a 4,390 cc Colombo V12 engine, specifically its Tipo 245/C variant. Although 168 examples of the coupé were built, just 20 spiders were created before its place was assumed by the 365 GTB/4-based Daytona Spider.
