George,
How do I do a leak down test and what will it tell me? I did in fact follow Russ' advice and have been using conventional Castrol 20W/50. Not much progress yet on the power front, I did install the new PI stainless mufflers, and according to my Gtech meter, I may have gained a bit of HP. With the car stationary and in the dark, I did run the engine up to about 6000 rpm. At that point it started to make a little different noise so I chickened out of running it any higher. I did notice a very slight popping sound, maybe too rich?, but other than that it sounded fine.
Thank you,
Art
