Twin Turbo BBC

[John McIntire]

I think that is why the OEM's use cast manifolds in their turbo setups. It's a lot cheaper, and they'll last forever. The only downside is looks and probably weight.
Look at the Banks TT kit, yeah its only for a SBC, buy the manifolds are cast. I think I remember reading here on this board that Banks was working on a BBC set up. We can only hope! There is a user on here by the screen name of "Slow4dr"(i think thats his name) and he works for Banks, guess it's time to start prying!
