Displacement + 13%, but the intake is not similarly improved (yet). Freer flowing exhaust headers (modest gain). Oldest of the DMEs holds it back.
I mostly built it to be durable. The race parts --especially bearings and nikisil should help it last. I can also add tweaks such as a chip/tune at a later date.
Truth is, my motor was so dead that even stock would probably be a startling improvement.
