area = PI x Radius squared = (3.141 x 2.25 x 2.25) = 15.901 sq in
volume = stroke x area = (4.375 x 15.901) = 69.568 cu in
Motor displacement = cylinder volume x # cyl. = (69.568 x 8) = 556.54 cu in.
A 540 uses a 4.250" stroke on a 4.500 bore.
A 572 is a 4.560" bore and a 4.375 crank.
A 502 is a 4.470" bore and a 4.00" crank.
Be sure you got the right pistons and rods to try to stuff that 4.375" arm in a standard deck block. Also plan on a good bit of grinding. Depending on what rods you run, you'll need to look closely at your rod to camshaft clearance - even if it clears with the cam driven by the chain you should double check to make sure the rods will clear even if the cam is stopped at the worst possible place (broken cam, etc..).
