Default Crankcase number

If anyone can help I recently got a custom Softail in a trade have no clue what motor is on it I can identify and without a doubt see that has S&S intake and S&S Super E carburetor but the motor is not an S&S motor the crankcase number is Bklx923445* it has BDL belt drive primary with a Harley 5-speed transmission I'm not sure if it's a Harley crate motor if it's a revtech motor or if it's a Ultima motor

From this 2009 thread: https://www.hdforums.com/forum/gener...ml#post8564011

BK = model designation = FXSTC = Softail Custom
L = 80 cubic inch (1340cc) Evolution engine
X = model year = 1999
9xxxxx = sequential production number
