Hi Bruce,
Good to hear from you. As I mentioned above my engine has about 10 hours on it. For a quick review, it is out of an '84 T'Bird and has forged pistons, reground cam, new lifters and push rods, Beecher underdrive pulleys, Blanton redrive, modified water pump (larger impeller and backing plate), Holley 350cfm carb, Ford sandwich oil cooler, short exhaust stubs and the expansion tank you welded for me. It is hung on the airframe so I can start it up and run it whenever I go out to the airport, which isn't too much lately. Initially my goal was to get it running and keep it cool. I hung a radiator out of a 3.0 Taurus vertically about a foot under the motor. I mounted the fan from the same car behind the radiator. Coolant temps were Ok but oil temp kept climbing. Then I hung a copper/brass radiator from a 280Z horizontally under the motor with the fan on top pulling through the radiator and blowing on the engine. I also mounted a stacked plate oil cooler under the radiator so the fan could pull through it. On hot days coolant temps stayed at 185, pressure was less than 10 and oil temps stayed a few degrees above coolant. Everything was perfect. Then I changed it. I installed a new aluminum radiator in the tail with a larger fan. The stacked plate oil cooler just hangs up front with a computer fan pulling air through it. I also installed a sensor and relay to control the cooling fan. The coolant temp is still fine but the oil cooler needs more air through it and the coolant pressure is all over the place. Spark plugs look good except #5. It is silver gray. I'm putting in some Bosch platinum +4 plugs this weekend. If anyone wants pictures let me know. David |
