The small block bolt pattern will be different. I would see if the size and splines on the tranny input shaft will work with existing clutch and bellhousing. If yes. you just need to worry about bolting the tranny wings to the bell housing, rear tranny mount, and driveshaft size. If the input shaft is different. then see if the heavy duty clutch assembly will fit in the small block bell housing.

What kind of Trans is it?? If it is a ZF trans there is no chance what so ever. If its a different type like a T18 you can change the bellhousing but it still might not match up.
