Wanna share more info on these other motors that have afr heads and 10.3:1 compression ratio with a street roller cam making 680hp, seems kinda high, but you never know and I'm planning on building a 427w this spring/summer, and the more combos I hear the better. Thanks. And your chart looks good to. I'd like to get 550hp out of mine using hydro roller cam and afr 205 heads, and be streetable.
