You’d have a rod to stroke ratio of 2.29 and if you ran a car with over 270 advertised duration you’d never get the valve notched deep enough.
You could make the piston thicker at the valve pockets but you’re just making the piston heavier than it needs to be.
If it’s an unlimited induction class I’d shoot for a R/S ratio of 1.60-1.65.
If it’s an induction limited class then I’d be lookin at a R/S ratio around 1.80-1.85ish.
That’s IF I could pick the deck height.
That would be a 5.000-5.525 rod for unlimited induction and 5.600-5.75 rod for limited induction.
And whatever deck height I would need I set the pin height at a reasonable position so I don’t compromise ring seal.
My guess of a 9 inch deck may be a bit high for that length of connecting rod.
