Above engines in a 28 stepped hull.Would sit higher compared to twin B/B.Should still run 78-79??

Was just thinking about it today.to the best of my knowlege no 28 has these engines.

Perfect set-up period.
My 28' had twin small blocks and it was extremely well balanced. On a new stepped bottom 28' that set-up would rock.

Hell ya. Would be perfect fit. I considered putting one of them in a 24 single.
