I was reading recently about NHRA pro stock from 2014 when they still running carbs,
With steel rod they were around 0.050"
Aluminium rods around 0.060"
They considered quench still a important tuning tool even at 16.1:1 compression or so.
I calculated at 9000 rpm your engine will have avg piston speed of approx 5625 fpm
This is where piston design,weight,wristpin quality and oiling of these areas is critical for longevity, seems drag racers can get away with alot of different things
