I have seen quite a few post where guys are using Yates C3 heads on different set-ups, but not one of them have made 900 or more hp naturally aspirated. Has anyone made 900 or more hp using C3 heads? Many people say "they will easily make 850 and so on", but they never say "you can make 900 or more with them." The SB2, SC1, D3 and other small block heads are making serious hp. I know the C3 isn't in the same league as the heads mentioned, but are they capable of making 900 hp?
