Short of a 1000 gallon tank and a 4" dump valve, you wont gave enough compressed air volume to do anything

Pull the drive and look

Update!! So i used a snap on boroscope and found no old flappers in the exhaust.... Passed the raw water test with flying colors....... Pulled thermostat and,,, walla,,water coming out everywhere,,,,boiled the thermostat did not open till 180, also possibly my homeade thermostat gasket may have kept it from fully opening....leaving thermostat out and heading out this weekend,,,thanks again guys!!

Don't do that! Those engines need a thermostat. Bad things can happen if you don't.

[Lowchopr]
