pipe popping

Did a compression test and a leak down. Here's what I got.

Started her up and got it to 155 degrees. A little warm, but not warm enough that the popping from exhaust stops. Do a compression test and the results were astounding.(in my book).
Low of 174psi and a high of 178. Cranked each cylinder 5 times. I was pretty impressed. I've been doing these tests since 1976 and never had one that consistant. Maybe a testament to Brian's engine builing skill?

Time for the leakdown. Had to buy one since I never had the need, so I bought an OTC Dual gauge from Summit. Read all the instructions, blah, blah, blah, and Holy Crap!

According to the gauge, I have roughly 33 percent leakdown each, in all 8 cylinders. It's so far off, their chart don't even go that low. I cannot for the life of me believe those numbers. I could hear a very, very faint leak through the breather every cylinder. I had to turn of my stereo and heater and put my ear to the damn thing to hear it.
Never did hear a leak through the left tailpipe. Which is good.

This thing burns no oil, doesn' smoke, hardly any blow by(Total Seal rings), and hasn't lost any power from day one. Still brutally fast for a street car.

I'm thinking either: A. did the leakdown right after the compression test. Maybe the raw fuel washed the cylinders of oil.

or B. engine was pretty cold by the time I did it.

or C. my new OTC leakdown tester is a piece of crap

and finally D. Somehow I really do have a lot of leakdown and the car shows no symptoms.

Give me your thoughts. It might help me sleep tonite.
