probably not the best comparrison but I have done a few Briggs motors for racers that will happily do 7000 rpm.
Once you take the counter weight off and balance the crank, there is not all that much difference.
Latter engines will toss the piston if you don't fit a stronger rod however the earlier side bangers will usually take 7000.
I have a friend who races go carts and gets two racing seasons out of a Chinese Harbor Freight engine. All he dose is remove the governor. He never wins but has a lot of fun without spending big money. Maybe the person using the Briggs engine wins???
