who to machine T/A oncenter block

also can anyone tell me if the alum block will need to be clearanced to fit my crower 6.00 rods with a 3.625 crank before I try to mock it up? also what about cam clearance with the crower rods?
It’s very highly likely that it will need some clearancing. If your lucky the cam will clear but you won’t know till you mock it up.
