depends what engine and heads and load. what engine are you talking about? What car? do you plan to pull a trailer? what gear and trans?
If it is a 454 with stock iron heads then I would say no.
if it is a 350 with flat tops and vortec iron or aluminum heads then I would say, no problem with 93 octane.
If it is a 1100cc honda then it would be ok too.
some of things that effect octane requirement are flame speed, piston diameter, head material, head chamber design, and others.......
10.3:1 cr with 195psi of cranking pressure means the cam is fairly mild.
would require 93 octane in most cases.
