P.S. Attention muscle gear heads: Do not fear the turbo!
I've done an aftermarket turbo install before, since we will be fabbing a new exhaust the only issue will be plumbing the oil lines, which can be done in a few hours easily. If this SBF is at all like a SBC we can tap the block off plate for the mech fuel pump for the return line (as I suspect we will be running an electric) and there are prob a bunch of places where we can steal the feed. Worst case we can T off the oil pressure sensor line.
Obviously it will be externally regulated so boost adjustment should be stupid easy. We might have to play around with vacuum lines to dial it in, but working with race gas we can always just lean to more boost
In terms of making it fit between the towers, it seems to me that we have some fine welders on hand, we have the Schorr metals scrap yard down the street, and I have a beautiful Craftsman mallet.
