Slant 6 stroker?

I don't know. I just don't think a longer stroke than 4.125" will be of any benefit. The 225 is already severely "underheaded" so adding additional cubes from more stroke I think exasperates the problem. I think a head like the one I have is probably real close to a "max effort" slant 6 head. I'm really wanting to see how it runs, but even it will still limit the engine. That and the lack of being able to really get the bore out big enough. I'll be happy with "whatever" it does, though. That's just the attitude you need to have, because they won't ever break records naturally aspirated. I say that, but then look what Mark Etheridge has done. Does anyone know if his records have been broken?
