Thanks Boss,
In my area there are two Fuel choices:
93 with 10% Ethanol or
90 with 0 Ethanol
Which would be better suited to:
The Engine is highly modified with FAST EFI,Comp Cams Solid Lifters Aeromotive Fuel Pump and Controller 6AL etc.etc built by an now long gone Dirt Track Racing Shop.500 + HP 10.5 Compression.
I'm more interested in reliability now that it has been modified with enough HP for me.
