What I did was to move the big heater core inside with 2-14" radiator fans to power it. Now I have a gigantic heater but without the underneath being blocked. If you don't want to do that, then just splice the radiator coolant lines so they run to the front, install a ball valve so you can truly turn it off in summer, and put a toggle on the dash to run the electric booster pump for the heater. I haven't had to use the electric booster pump yet-the engine water pump seems to do a good job. Good Luck, TomC
