This is a 1-piece rear main seal block. Factory 327 cranks are 2-piece rear main seal blocks. You'll need a 1-piece to 2-piece RMS conversion setup to use a 327 crank.
Why not use a 350 1-piece RMS crank if this is a budget build? Besides, there is not one good reason to toss away the displacement just to say "I got a 327!"- especially in a truck.
