I have just installed an M-1 procharger in a cruiser application. Prior to the install I had a hot water source from my 7.4 MPI. One side of the water heater hooked to the side of the block near the knock sensor and the other side went up front near the circulation pump. With the circulation pump now gone I have no flow through the circuit which I now hook into the base of the thermostat housing. Any ideas on where to hook up the heater?? The only idea I have come up with is to divide the flow (slightly reducing each)from the port side dump into the exhaust. Run one side through the heater and then return prior to entering the exhaust manifold. Looking for a better/simpler way.

Your motor will now run cooler so you will not have warm enough water to heat the water. Mine only runs around 110 degrees. If you can get the water after it goes thru exhaust manifold before it go to the dump you might be close to having warm enough water.
