I watched quite a few vids on compression ratio, David Vizard being one, and they alluded to a smaller bore can tolerate higher compression than a larger bore before detonation, ‘course I’m sure there’s a lot more that plays into it than bore size. I’m just puzzled, especially being the 350 has open chamber heads, and people saying those suck for performance. I’m happy so far I’ve pushed the envelope on compression for a pump gas 350.
