Sweet! That is a very impressive motor, with very impressive results.
I am especially impressed with the changes made to improve oiling to the lifters. I was under the impression that the Dart block did not need these changes.
What is the reason for the bronze bushings for the lifters? Longevity? Reduced friction?
You didn't mention it, so maybe you already did this. For street/part throttle driving, it's very important to get the throttle bodies perfectly balanced with a synchrometer. If you don't, it will never run right at part throttle under a load, and no amount of tuning will get it right.
I had to figure this one out on my own. I find I need to adjust this about twice a year.
