a built motor basically has:
low comp(for turbo or
pistons
forged connecting rods
crankshaft
iron ductile sleeves
that's the bottom end(the block)
top end(head):
upgraded valves
upgraded valve springs
upgraded retainers
upgraded rocker arms
upgraded camshaft
cam gears
there are other things you can do to further build it(block guards,gaskets,port and polish,3 angle valve job)
it really depends on your power goals as to how far you have to build it.
