Octane requirements for nitrous and high SCR?
New build is a 434 with ported 670 iron heads at 9.8:1 compression. Lunati 231/239/110 on 104.5 ICL. With an intake valve closing of 65.5* ABDC, the DCR should be about 7.8:1.
What octane fuel should be used with a 150 shot of nitrous? Single stage plate under a Q-jet on RPM intake.
