Question about RamJet 350

Just a question about RamJet 350

GM recommends 92 Octane
I live in Southern CA and 91 Octane is the highest in my area. The Engine is for a Truck / Panel Truck and cruising.

Is a difference of 1 lower Octane going to cause any long or short term problems?

I would not think it would be a problem with 91 versus 92. There probably is that much error in the calculation of octane rating. There is a firm that makes a programmer for the Ramjet controller and if it is a problem you could use it to detune a bit.
