Just because you cant hear detonation does not mean it is not happening. Go put it on a chassis dyno and load it make a pass, then drain the gas run it on 104 race gas and see what it does. Bet it picks up a bunch because it needs more octane
Cliff you got many 455s running 11.2:1 iron heads on pump gas for a street car?
Those 11.5 NHRA stockers using low compression 78 motors sure got it figured out! But the chassis and cam are definitely not too street friendly

I admit this is a possibility. However, I've had a bore scope up it's skirt and at least with the crappy resolution from the camera the piston top doesn't show any signs of damage. I was even able to pull the part number off the piston.
L2359 which corresponds to the Sealed Power forged slugs for 4.181 bore.
One thing of course working in my favor here is my location. I'm 4500 ft above sea level.
