The Turbo 400 began production in 1964. It was used in the GM car and truck lines and has several bellhousing styles available to bolt up to the popular Chevy and BOP (64 and newer Buick, Olds, Pontiac and Caddy V8) engines. Also available was a rare bellhousing style to bolt to a Jeep. The TH400 has been used in vehicles as powerful as the 1970 Chevelle SS454 with the potent LS-1 Big Block. The 400 can take a LOT of power!
