Not really recommending anything, just pointing out that a 455 with aluminum heads will run fine on pump gas. My last 455 was 10.48 to 1, the current engine 11.3, and both have zero issues anyplace and dead solid reliable on currently available pump fuel.
You just didn't put enough camshaft it that engine for the compression, not to mention it's not taking any advantage of the head flow available. You'd have made just as much power with a set of 6X-8 heads on it and that cam, and it wouldn't be pinging either.....IMHO......Cliff

Cliff,
What cam are you currently running in your 455 combo?
Thanks
