1984 Camaro Z28 with small block 406ci. Take it off my hands!
 

Here is the story on this car. It lost oil pressure at idle. Pulled motor. Replaced bearings, mains and rods. New rings, cam, lifters and push rods, oil pump and pickup tube. Started it up and it has a knock at 2000 RPM and up. No knock at idle. Checked lifters, rockers, push rods, distributor, fuel pump shaft, oil pump, main bearings and rod bearings. All good. No clue what is making the noise. Had two mechanics listen to it, they cant tell what it is. Oil pressure is good, runs strong lots of power. The spots under the car in the picture is NOT oil, its water just washed the car. I'm done screwing around with this car. I wanted $6250. I will sell it as is for $5000. If I don’t sell it soon I will pull motor replace the pistons and keep it. The motor is a 400 bored 60 over. 17 inch wheels, racing buckets, new suspension, 5 speed manual. Has only about 5 miles on the engine just from testing it out when it was put back in.
