Holy Mackerel! that is flat out awesome numbers all the way around.
I am reminded of what a race official said to me at last June's Fast Fords. "I just can't believe how the guys constantly thrash these Y Blocks!" We gained a lot of respect among the FE crowd. They were impressed by both the horsepower output and the abuse that the engines were receiving - without catastrophic failure. The only issue I can recall had to do with a driveshaft that got wrenched in two!
