Heater core hose ?

I have a 81 Buick Regal that I swapped in a SBC 350. I also put in a new/bigger radiator. From the heater core I have 2 hoses, but I only have 1 place to put a hose and thats on the intake. Would it be "better" to Run 1 hose to the intake and install a T. Or should I change the water neck to a neck that will accommodate a hose?

You won't get any flow if you run both hoses through a T (no heat).

You should have a nipple on your water pump as well as the intake, possibly the radiator as well.

Generally, any hose/nipple behind (toward rear of engine) the water pump is delivery and any hose/nipple in front of the pump is return (RWD). In other words if you hook your hoses to the pump and the radiator, you'll have little/no flow as they are both "suckers".

Using the nipples on the intake and the pump are the best configuration. You get hot water (heat) the quickest and it acts as a bypass.

Heater Hose

You should on a SBC have a place on the top of the water pump to install a hose fitting or on the side. Should be a large allen/pipe type fitting. You can get these fittings at any parts store. 1 on the intake and 1 to the water pump. That will complete the flow. BstMech right you don't want to put in a "t".

If both ends of that hose are connected to the engine, you have 2 fittings. Hook one to each pipe of the heater.

Hose?

Here is a picture of what I have. I will connect one hose to the intake, but should I put a nipple on the water neck or on the water pump? (Or does it just not make a difference)

ok do this its exactly what it did it works
look at your picture, look at the two arrows pointing left, run a hose from those two nipples to the other one. they flow together. the hole will have to be kind of long to fold around like that. approximately 2 1/2 to 3 feet long. also refer to my pic to see what the final product looks like
