Can't go wrong with a shop who has a good rep with the circle track guys "supers"
Unless you are looking for a little more bottom end ,personally I'd stick to 0 on the cam.
Are your heads set up to run unleaded ?
I ran low lead 110 in the 12.5:1 engine I had in it, would run on any lower + pre ignition. I bought it in 55 gallon drums ( cheaper than the track)
Now..the 302 at 11:1 liked race fuel, but would behave on high octane pump gas---I like the smell of race fuel, and that's what it's getting when it's back on the road. I'm not commuting with the car.
Someone already posted in another thread about mixing to a point were you have no pre-ignition...good advice. I imagine 50/50 would give you : (110+98)/2 for your average on octane.
What ever you do ,I don't think I'd tune the car to try to make it run on cheaper fuel, tune for performance and match the fuel accordingly $$$---that's why they are called toys.
