    The bellhousing was once used with 4 speed transmissions in 66 – 72 Chevelle, 66 – 81 Corvette, 67 – 72 Camaro, 68 – 72 Nova, and 64 – 81 Impala, but with any GM transmission that measures 4.675″ and an 11″ Seize, it’s going to fit great in all the additional applications shown above, in addition to many several types of projects. This may occasionally make it a snap to get that massive GM bellhousing on your muscle car or rod project. This new Chevy high performance 11″ style aluminum bellhousing was once issued on Camaros, Chevelles, Impalas, Corvettes and Nova’s with big block 396, 427, and 454 engines, in addition to Yenko, Copo, and ZL1 and in addition small blocks like 302, 327, 350 and 400 with the 168 tooth, 14″ flywheels and 11″ clutches, including Z28, Yenko, and Deuce models. Will settle for your original Muncie or Saginaw Manual Transmission with a 4.675″ O.D. bearing retainer. Can even work with the Tremec 5 and 6 Speed Transmissions. You’ll use one of the crucial new bolt-in Classic Car Conversion Transmissions and still use all the Stock 4 Speed Pedals and Rods with this bellhousing.
