If low cost power was the driving force here I don't believe this forum would be doing as well as it is. This is more like a let's see what I can do with what I got and do it better than anyone else. I personally like the uniqueness of the inline power plant, I have several vehicles that are in one or another unique and have rebuilt or rodded them because I don't want a sbc/th350 '32 Ford or '55 Chev. So money permitting the aluminum 12 port head would add to that factor. But this all just my personal opinion.
