BBC Swap- Need help with heater hose question!!
I finally got my 454 swap motor in and bolted up. Just a word of advice for anyone doing this swap and wishing to put in the hooker swap headers. Be prepared for a fight comparable to 300. NOT FUN!!! Anyways, I am starting to hook everything back up but I came to a speed bump. I've got the two heater hoses and need help with which hose goes where. There are two heater hoses, I believe one is 5/8'' and one is 3/4'' from firewall. One goes to the intake port and one goes to the radiator port on the passenger side. Question is which goes to which port. I am pretty sure that the smaller diameter goes to the radiator but I would like to know for sure. I figure some one out there will have the answer. Thanks Guys!

To put it a different way, the smaller 5/8" one is the "supply", and connects to the intake manifold. The larger 3/4" one is the "return", and goes to either the nipple on the radiator tank, or the water pump.
