Thanks for the reply. That's kinda the info I was fishing for...as in what is a "safe" (generally speaking) total timing number.

Now that you mention it, I think he said he was getting some sort of pulley setup that once you change it once, you can simply unbolt the actual pulleys for any future pulley swaps? I assume he means a 2 piece pulley conversion, which would have made way too much sense to swap on when I had the snout off replacing the coupler a few weeks ago...

He regularly drives around on fumes, so starting with an empty tank won't be an issue...LOL.

Again, generally speaking, do these cars automatically scale the fuel curve, to a point? I'm hoping he gets a WB setup on there because I definitely don't want to trust the NB O2 sensors on a boosted car. My truck was right on the money, but a supercharged setup is not something I want to just start randomly changing things on.

Any other tips or advice is greatly appreciated. The plan is to head to the dragstrip on November 15th. I go to this end of the year event every year and got him a spot this time around.

He won't be whooping his Dad just yet, but I'm sure he'll have some fun.
