BH10003 Olds & Cadillac Bellhousing

$345.00

This cast aluminum bellhousing fits an Olds (1949 thru 1964) or Cadillac extended bellhousing engines(1949 through 1954). These bellhousings are NOT meant to exactly replace the stock bellhousings. They are made to accept a GM pivot ball and cast steel fork. We can machine them to accept most commonly available 3, 4, and 5 speed transmissions. We also have extended pilot bushings available for different length input shafts.

This part is over 1/4 inch thick making it the heaviest duty bellhousing available for these engines.
