What engines have 4.75 stroke at 8500 RPM?
Typical 632" BBC. Typically they get limited by cylinder head choice via rules, which is why they only turn 8500.
You can go buy a 903" nitrous motor from Pat Musi... Of course you are going to use a 5.3" bore center block with matching cylinder heads that flow 650+ cam intake ports on that 12" deck height block. Bore is almost 5" with a 5.5" stroke crank and they are turning 8k plus....
Pisron speed is a nice number to have but much like a good rod ratio discussion, which the proper answer is 1 connecting rod to one piston, is just bs for the most part.
