I lucked into my order - cam first then gears (just got the gears done and have had the cam for 10K miles) because honestly I didn't even think about gears (the 1LE 3.91 gears were not on the radar when I did the cam and the aftermarket gear sets were really expensive). However if I had it to do over again I'd do the same - cam then gears.

The cam made the car. It feels great, sounds even better and the kick as the cam climbs onto the power curve is addictive. So far my early impressions for the 3.91 gears are they are the icing on the cake. Now the car is responsive in every gear at low rpms and of course the kick from the cam is felt even more.

Either way you can't lose. Both are excellent mods for our LS engines and heavy azz cars.
