Of course, the OEM SB is but one of the components that prevent me from going past my current power. It's not designed for these levels. The thrust bearing first comes to mind, as do the cylinder walls as you discovered.

BTW, people come here for the "spice", which is actually just greater details about our cars. I don't see a garage or any delineation of the details of your car here. How much of that are you willing to disclose here so we can do more meaningful comparisons just for fun?

It might make a little more now with some recent changes, but I wanted to clear up that a $60k race engine was required to make that power. That old engine made 29.5 psi before it died.

FWIW - going from my SBE with ported stock heads to the 416 with CID heads I didn’t gain anything on the dyno. Made 1,119 on SBE and 1,117 on the 416. Different days obviously, but the same dyno. That was an unported 2650 running on C16 with a 9.45/2.75 combo. In hindsight there is reason to believe there was belt slip but it wasn’t obvious in logs. I have trap speeds and weight to stand behind those HP numbers, unlike some others. ;-)
