Different but information to ponder. I useed to get my racing engines ( circle & Road Course ) built for the two venues. The one thing my
builder told me each time was: Stay above or below a certain RPM, like 6200, or below 7000, always different. A flex plate and balancer issue combination would rattle your teeth. Be well, wish for your success.
