hey guys, i am putting in a 350 block from my old 305 block in a camaro i just got... we have the normal coolant lines that go to our heater from the radiator (smaller line of course) and one that goes up by our t-stat right?

i have an engine from a 91 chevy 1500 (350) being put into my 84 camaro with a 87 chevy 1500 (305) in it already (dont ask, thats how it came lol)

here is a pic i drew to just explain what i mean. any help is appreciated.

the nipple by the dizzy has a line that comes out of it (1/2 wide, maybe 3/8) and then goes into a 2 that looks like it feeds into one of the other 2 nipples? thats how it was cut and given to me.

both are carburated

 

I'm not totally familiar with what the trucks do, but for the Camaro, you basically need hot water coming from the engine to feed the heater core, with a return to put it back in the system.

The hot water comes from the nipple on the intake manifold by the thermostat and is fed to the smaller nipple (5/8") on the heater core. The 3/4" line coming out of the heater core is the return, and whether you put it to the water pump or radiator is up to you - both are on the "suction" side of the water pump.

 

and thats because cars go rid of that old suction line at the radiator!!! ah hah! hmm... now just the question about the T at the back of the block... i am now thinking of doing something like the pic? and what should i do about my radiator? block it off at the suction? or should i block off the water pump? or get a t? i dunno lol
