Best Answer

If off a transmission, then it is for a Borg Warner Super T-10 transmission with an aluminum case. The gear ratios can be determined by the number of grooves in the input shaft. 2 grooves equals a "close-ratio" design (2.43 first gear) and 3 grooves equals a "wide ratio" design (2.64 first gear). Although it is a Super T-10, the aluminum cases are not as relaible or strong as the nodular iron case.

Casting numbers on top of the bellhousing flange and the suffix number on the block deck in front of the passenger side head. The casting numbers will tell you which block casting you have.
