IMO, you’re unnecessarily close. The thing people forget is, during high, RPM operations, the piston will stretch the rod. How much stretch there is depends on a few factors, but do not kill yourself that the rod will stretch and stretch a lot depending on what going on in the build. a heavy piston on a heavy rod at high RPMs can’t move that rod a good distance.
Like I said earlier, the street or bracket engine that has an extra 10,000 clearance and quench will not be noticed. The difference between 30 and 40 in clearance is not going to be picked up. Will it show on a Dyno, yeah probably I’m sure. Do you need the extra 357 hp?
Run what you want at your own risk. I can’t be a fortuneteller. I adhere to some safe practices myself. I’d really not rather gamble my money away on a minor power gain by closing up the quench.
