Lt1 sawp and heater core etc.
Okay I just got my 87 Iroc with a LT1/4l60e swap already done. Now the heater is not hooked up in it. There are two hoses off the motor that are blocked off and since they are starting to look kinda dried out and its cold I want to hook it up. Now i dont know what the stock hosing looks like since i didnt do the swap. how do I run it from the motor to the heater core. And what size hose tdo I need (i havent had time to really look at it).
Also the next thing. The blower motor only blows thru defrost and doesnt work when on HIGH. The ac is not hooked up also is this why? Nothing comes out of the vents? I guess I will start with the relays and go from there but does anyone have any input?
Thanks
Jay

After reviewing pictures I figured out the heater core...now just to takle the blower motor. I dont see any vacuum lines under the hood near the passenger fender either.

There should be one long vacuum hose coming out around the A/C box, I took it and hooked it directly to the intake, works on all settings now.
