ok to save soem money:
radiator: go to autoparts store pick up a:
heater core a 1977 pontiac boneville broham edition with ac with the 4XX ci block motor. $22
tubing: home depot 1/2 id clear tubing 4 bux for a 10 foot roll and it doesn;t kink easly at all due to thickness. $4
water blocks-- watch ebay save u big $,
also one thing to remeber to avoid corrosion between your water parts is if you;re using a copper radiator then everything else should be copper an aluminum radiator everythign else should be aluminum, when u mix alum and copper u get nasty nasty effects in time.
and to andswer your question, no i asked the same question about a month ago and got the same answer. buy seperate blocks. and stick to 1/2 id stuff more flow better cooling.
