What rear gear is suggested? I was thinking of a 4.10 or 4.56 with 28" tall tires. . Thanks

Well you came to the RIGHT Place..
Another person is preparing a 93 Camaro on Class Racer.
Bullet has a Pure Stock Cam and Spring Package that will pass tech.
Even that it is about done by 6000rpm..
I am adding a Yank PT 4200 replacing my Yank SS3800 Converter.
Since my car is driven to the meets they are locking converters.
4.65 gearing with 28 inch would work well.
Would spend the money to get a complete Moser Rear.
The small 7.5 inch rear is ok at stock power levels.
Send pictures of your ride and will post it on the PhotoGallery.
