This new Chevy high performance 11" style aluminum bellhousing was issued on Camaros, Chevelles, Impalas, Corvettes & Nova’s with big block 396, 427, & 454 engines, as well as Yenko, Copo, & ZL1 and also small blocks like 302, 327, 350 & 400 with the 168 tooth, 14" flywheels and 11" clutches, including Z28, Yenko, & Deuce models. Will accept your original Muncie or Saginaw Manual Transmission with a 4.675" O.D. bearing retainer. Will even work with the Tremec 5 & 6 Speed Transmissions. You can use one of the new bolt-in Classic Car Conversion Transmissions and still use all of the Stock 4 Speed Pedals and Rods with this bellhousing. Will not work on 1962-1967 Chevy II & Chevy Nova models as the size of the transmission tunnel is too narrow. Will not work on Monza or Vega as they both used a cable operated 10.5" clutch with the pivot on the other side. The clutch fork was also angled about 45 degrees not straight across. If your application requires a 1 3/4" Clutch ball instead, of the included 1 1/2" ball, let us know and we can switch them out at no extra charge. Click here to view the 1 3/4" pivot ball.
