so I have an 1984 base that im in the middle of a 3800sc swap. and I working my though it. and come apon an other problem that I sit and think about and read and read and some people have tired to tell me what they have done. but there cars are later models. I guess I cant do what they can. so I have the low alternator mount and woulnd like to use it if I could. but I want the ease of keeping it in stock spot. plus trying to figure out this heater hose running is something I cant figure out. my plan was to low mount alt. and freeze plug and water pump. and run a barb off lower intake but not sure how that works. how would it circulate? kinda lost with that. then iv heard I can just frezze plug both water pump and lower intake all together and tap into coollant lines and I kinda understand that one tap into out flow side going and tap back into in flow for return. I think that's how that would work?? im at the point where I don't understand what needs to done and about to just keep factory alt bracket and notch the deck lid. because I understand that.lol any help would be great or pics would even better. or shoot me a pm for phone number.

Have you read the thread entitled "automarshal 3800sc"? That's the way I plugged the water pump and threaded a fitting in the lim heater port. The return port would be incorporated into a hose that's provides for the secondary smaller hose to join it. I haven't found that hose yet but I'm not up to that yet either. Dan (FIEROFLYER) , can you chime in here as I need that hose info. And the info to put a "t" fill on the other main coolant hose.

I have an 85, which apparently means I have two heater hoses (I would think the 84 would too) instead of having only one like the later models. (I don't know the exact year cutoff) . I did exactly what auto marshal did and I have to find a hose that has a secondary smaller hose Y-ed into it to connect the heater return line . The heater feed line comes off the lim port that auto marshal put the Home Depot elbow on.

I just his build. and he said if he had a 84-87 that he would have just ran the hoses from the factory ports. 88 is the only year u can run them like he did from what I understand.

Use something like this on the return pipe to the water pump and hook the heater return into it. Thats what I plan to do.

The LIM port (as in automarshals thread) goes to heater feed .
