Overall, I'm hoping we can fix the 174, it'll be plenty of power for hooliganism and rather cheaper overall. However, the idea of a TT is kind of exciting, so if the 174 doesn't work it'll be fun. Running E85 with even a pretty moderate TT setup, pushing 650BHP out of the 302 with the new heads shouldn't be that difficult. And then, boys and girls, we have a bit of a beast on our hands.

The main support and the valley girdle are two different things. The main support ties all the main caps together. The valley girdle is like a truss that stiffens the valley to help keep the block from flexing.
