We came across this 1985 Ferrari 400i being sold at Barrett-Jackson Las Vegas 2015 while researching. The car is powered by a 5.7 L LT1 V8 and four-speed automatic transmission from a Corvette. The car was built by Roselli Foreign Car Repair in San Jose, California. It sold for $49,500 which is pretty good considering a concourse quality version is valued at $41,300.
