Performance Distributor in Stock Engine

I'm in the process of putting an electronic ignition on my '67 Barracuda. The engine is a 273. Everything is completely stock except for an intake/carb. Is a distributor with a high performance curve ok to use on a totally stock engine? Specs are as follows:

Less than 4 deg. mechanical adv. below 650 RPM

approx. 8 deg. at 950

Approx 13 deg. at 2500

Vacuum: near-zero at 10" vac, then 9-10 deg @ 15"
Those numbers dont look right, the total advance would be to low for a stock engine.
I would talk to Don at FBO Ignitions. he is very good on Mopar timing requirements.
