These high horsepower high rpm engines appear to have lots of durability issues and not probably the way to go for the weekly racer. A few bonzi hits in the Fall and a couple of Mopar racers a year maybe
I have just under 2000, yes 2000 runs (in 2.5 seasons) on my 358 and haven't so much as adjusted a rocker arm. And yes, I buzz it every run, both in the water and throughout the run....9200 thru the lights. As for a bracket engine, I can't think of a better way to go. Oh, and thats 176 mph at 1800 lbs.
