My 1964 Mercury Montclais has the 2 barrel 266 hp big block FE engine. The car has sat for twenty years, since July of 1986. I've only had it a week. I started it up Saturday, 2 days ago, and I heard what I thought might have been piston rings scraping on the drivers side of the engine. But when I sat inside the car, the noise sounded almost like a flywheel problem. I have a short video of me starting the car on my Youtube channel, Southern Mechanics. Please watch it and let me know what that noise its making is. You'll see the car in my Youtube channel picture. Thanks.
