I really like being able to post an idea, or thought, and have you guys teach about why it canīt be done

I reckoned it would take $20k to make power at the top end though.
Blykins; to flip it the other way then - how should I spec a 289 around webers, for mostly backcountry roads cruising and the occasional track day - and where would such a build produce peak power? How far up could that be pushed and not make stupid compromises to the streetable part of it?
