well too the 1929 for another shakedown run, keeping them to under 30 minutes and 10 miles. this one was 15 minutes and around 7 miles round trip. Flat land, one small overpass.

today was a beautiful day, cool temps around 75, nice breeze blowing, low humidity. A near perfect day.

took the car out for a run, and about 5 minutes down the road there is air in the Gano, i can see it clearly while cruising steady at any speed. 15, 25, 30 !! then when i stop i can see it burping up. a wave of air bubbles, break air bubbles, etc... over and over while sitting only for a minute. take off and can see the air bubbles in the coolant, does not matter that i am slowly accelerating or not. coolant level was just above core in radiator. stopped and check temps, return line is about 170. top of radiator is around 180-190 bottom is around 150-160. cylinder walls read around 200-215.

get back home and park in driveway, and air ensues, same as when i was driving.

1929 Chevrolet International AC - Engine Shakedown 3 19 Jun 22

while testing and playing with the sideview mirror, i did my second test drive after timing. car started right up, ran strong, good acceleration, etc... temp was 80F low humidity, and at dusk. drove the same 1.5 mile 5 minute trip. when i parked in driveway temp on radiator was around 180F at the top 150F at the bottom. no puking when i shut it off. there is still air bubbles when not at idle, not as bad and only when it warms up.
