need help for rotating assembly

hi all!
i have a used velasco hemi crank with 3.530 stroke that the Velasco company said they originally built for a racer that ran unblown nitro(initials BR stamped on the crank).
it is in pretty good shape and wish to use it in a blown alcohol application.
could someone running an identical stroke crank give me some infos on the block deck height,rod lengh and piston hight that is commonly used with it?
just being curious:what static compression do unblown nitro racers use?
thanks for any input

 

you need to check the bob weight..Dave

 

stamped infos on bobweight say:
B-R (initials of the racer the crank was built for)
2885
0509

then on the other end of bobweight:
426
3.530
