This 11" Performance Cast Aluminum Bellhousing is a reproduction of the original 3899621 bellhousing used on GM models with Big Block & Small Block engines equipped with an 11" clutch. This performance aluminum bellhousing does not have the GM Part # 3899621 casting number but will look, fit, and perform just like original. If you are doing a restoration of an early muscle car, or just want the correct bellhousing to finish that rod project, this bellhousing is the perfect part!

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
