Octane Question?

Octane Question?
does anyone know where I can get some information on octane needs for performance engines? I bought an LT1 that has about 570 n/a at flywheel with 3.5 crank and 12.8:1 compression. I was told it was built for alcohol, but I am wanting to make it more streetable. I need info, so I can figure out how I can run on pump gas.

Re: Octane Question?
Octane requirements are determined largely by "dynamic compression ratio", not be static compression ratio. Do a "search" an "octane" and "DCR" and you should be able to find discussions of the DCR limits for various types of fuel.
