Another timing curve question

It's not so much that I'd need to trust the gas-pedal-presser, but more of a "did I build that bottom end tough enough". At least I don't have to worry about a steel fan blade, but I REALLY don't want to be standing next to the engine with the hood open, if a rod/piston comes out the side of the block :eek: Probably will be shifting at 6500 if not higher...

Anyway, I have long believed that "Any fool can write a check". But there is great satisfaction in doing it myself, even if the results aren't perfect. Except the paint. I tried that twice and learned my lesson ;)
