454" 4.185x4.125", Small block, B1-MC's, E85, 12:1, .619/.641 274/280@.050 "street" roller. It was a good combo til it broke a rod and cracked the main web in my R3. Lack of block availability turned me off from building it again.

Not sure about converter flash with the new combo yet, probably not 5800. I might go test Friday to answer some questions about jetting, timing, shift points etc.
