Coolant modifications
If I were using a performer intake with blocked exhaust ports and a carb with an electric choke to further modify the intake I would weld up the exhaust crossover ports in the intake. Then drill and weld (2) 5/8's bungs on either side of the crossover and install hose bibs in each. Run the heater return hose to one side and on the other run in back to the water crossover. Now to be really proactive in your search for the truth... install a hot water valve in the hose leading to the intake from the heater. The valve is activated with a push /pull cable. Install with cable pull under dash. Cruise with it open and close when you want that extra HP at the track or strip. Ed
