3.0 Engine History

[jamesjedi]

I am looking at an engine that was used for an open wheel auto-cross car. he reversed the ring gear and hung it off the end. Is this something I should be concerned about? Would it require him to have made a structural change to the case/crank?

>behind a TUI BH-3 Super V and ran it in SCCA Solo II B-Modified Class. BM at

Thanks for any insight.
