not trying to jump in on the thread BUT d-Stroking has been around for yrs upon years...Years ago they had a CI class in which they compred cubic inch per body weight..( which in my opinion is the correct way to do it ) ...but todays world people stay far from that idea beacuse everything has moved toward the opposite end of the spectrum...a 565 or 582/598 is being considered small motors this day and age..Hell i HAVE EVEN HEARD 632'S BEING CALLED SMALL MOTORS.....
but for the record i have an uncle that holds a NHRA record in a stock class with a s-stroked motor under 380 ci in a 3500lb chevy wagon..he backed up a a pair of 7.50's (1/8 th mile)....ohhh yeah he turned it 12,000 rpm...this was back in 1982...( this will give you an idea0
