Aight Bewy.......

I installed a mechanical oil pressure gauge under the hood today, because I am just curious about the oil pressure. 70 PSI idling cold and it doesn't rise one pound when I rev it, because I put the MP big block/slant 6 high pressure spring in it, so it's relieving pressure at 70 PSI as designed. Once hot, it idles at 60 and rises to 70 when I rev it. I knew it had good oil pressure, but dammit. lol

On to the "noise" that seemed to be spark knock. It's not. As I was revving the engine noting the oil pressure, I heard the noise right under my nose. It's the carburetor sucking air. Kitty said "That's the noise RIGHT THERE!" and she's right. Again. So no spark knock. I haven't had a chance to adjust the timing like you said. Kitty had a pre op doc appointment for upcoming surgery so we were gone pretty much all day. She has a stress test tomorrow with her heart doctor to make sure she's cleared for surgery, so tomorrow's a wash, to. Thursday, I'm gonna get on it and mess with the timing and adjust it like you recommend and see where it is after that.
