Hoping someone can shed some light on this one... Got a new my newly rebuilt 440 running... 30 over, forged pistons, solid roller, ported stealth heads, RPM intake, Demon carb, high volumn pump and Harland sharps. When I first fired up the motor, it ran fine with no strange noises. I shut it off and hooked up the timing light and vac gauge to tune and started hearing a strange knocking sound like a bearing. I shut it off and started lookin for anything hanging and so on. Found nothing. I was pissed and walked away for a day or two. I went back to restart the car and show "the throttle stop" (My wife) the car was dead and I wasn't kidding. I fired it up and there was no knock?? After running for a few minutes, the knock came back and would disappear while running?? There are times that it doesn't knock at all. Anyway, I changed the oil and had a flashlight beaming through the draining oil to see if I could see anything shiney. Nothing. I checked the magnetic milidon plug and it had nothing abnormal from a fresh engine. No flakes of anything. Like I said, the noise is intermittent. After I changed the oil and started the car, it knock pretty good and then it was like the oil circulated and it was quite again. I did check the converter bolts. When the car is knocking, if I hit the accelerator, the noise goes away, which would lead me to believe it is oil related. HELP!!!!:banghead:
