Thanks Jim, that would be great. I see you added a burnout to your little smily faced driver, how do you do that? 
I'll look forward to the new info, you guys have been a great help. I know i'll be asking a lot more ??? befor I get my 78 back on the road, thanks a bunch.

Appendix E of the 'Corvette Restoration Guide 1968-1982' by Richard Prince lists the following for '78s (all positraction):
Code OK - Ratio 3.08:1
Code OM - Ratio 3.36:1
Code OH - Ratio 3.55:1
Code OJ - Ratio 3.70:1
Hope this helps. Found the 'burnout smilie' on another site in a thread. I think it neat too!
