Anthony,
I am still working them out, but first I used the Richmond gear optimum calculator to get and idea of different combos. Then used either Smokemup and this one

With my experience on local race tracks I thought whats the point in having an 85mph second gear and evenly spaced around that when some second gear turns are around 55-60mph and the engine will be off the camshaft, so I am going for a lower set with speeds of:
7000 on 3.27 with 25.6" tires
56
80
106
134
164
Some race guys have second/third/fourth all about 15-17mph apart to accommodate these turns. We used to have an air force base with really high speed corners so it didnt matter so much. Another point I am going to run more of a revver whereas if I went to a 406 race engine ratios would be less of a problem due to lower down grunt.
