Greetings to all: What are the best HP/TQ figures anyone has managed on 91 Octane gas?

(Assuming no better than 10% eth.)

Stock block, what mods?

Actually any mods. I was interested in how much HP 91 octane gas can support without detonation.

It will be something like 12 Lbs boost, 19 Deg. timing and 550 HP.

Even if you had a $10,000 short block and stage 3 ported GT 4V heads, long tube headers, twin 600LPH fuel pumps, 1/2" fuel line.....etc.
There is a limit that 91 octane pump gas can get without detonating. (I just do not know what that is)

Thanks, Miz

You won't see that kind of timing on 2v heads

Going for max power on low octane is a fools errand. That said, I know some 600+hp cali trucks
