Glad you liked everything.
After having dynoed, datalogged, and open tracked a bunch of 5.0s I'm not crazy about high timing on these engines on pump gas. I generally give the KS about +/- 3* leway, on most cars it will start out with 12-14 and add some timing, but on some it runs in the middle.
You can often get away with an extra couple degrees on the dyno and show 20-30rwhp more.
The good thing is once you get into that timing range they can take a ton of abuse, I've opened tracked my TVS Boss on 91 oct with 230F coolant temps and 150F intake temps and it's been happy with 13-14* with an 82mm pulley/10psi. I've found the same with Jeff Lacina's VMP TVSed GT that he open tracks, and he driver harder than me.
I find a little torco goes a long way and lets us get into the 18-20* range very safely.
