Heya Jason
Yeah, I've got the 'ping' to about as minimal as I think I can get, but it's still there. I'll give it another try later this week and see what happens. Other than messing with the dist, it's running schweetly.
I found out what the exhaust leak was too - woohoo - one of the gaskets between the HE and muffler is crapping the bed. No worries, phew- I tightened it up and it helped a little, but at least I'm not crazy. Well,.........
I also noticed something about this setup - it seems to respond the best, believe it or not, to blatantly mashing the throttle! Yeah, it runs fine if you're puttering around, but really wring it out and it gets up and rocks - x-way on ramps are a blast, I can finally feel acceleration (and HEAR it, thank you Monza). It seems to WANT to be run hard - instant smile machine!
It runs best at about 180 oil temp, 45-50lbs pressure, 300 degrees head temp, and 3000 to 4500 rpms. It sounds awesome, I know I keep saying it, but DAAAMN.
