How many Chevrolet Camaro Z28's with the 5.0 liter TPI V8 and the 5 speed transmission with option code G92 were produced in 1992?

607 is the likey number. There are no known published numbers on how many Z28's were produced with the G92(performance axle package) and the LB9 (5.0 liter) TPI V8, but the numbers are few. According to production numbers, 70,007 total camaros were built in 1992, only 6,451 were Z28's.
To arrive at the answer to the question, we must consider the fact that all 3038 1992 camaros built with the L98 (5.7 liter) TPI V8 all included J65 4-wheel disc brakes as part of the build package, and all were automatic transmission. All G92 camaros included J65 in their build. There were 3645 J65's built, but only 3056 G92's. The difference between the two were the 589 B4C's (police package) which all included J65 and included the performance axle rear-end, but for some reason did not include the G92 on their option code build sheets despite having the option included. If you do the math (take the 3645 J65's and subtract the 3038 B2L's), that leaves 607 left that were the LB9 5.0 liter and the 5 speed transmission with the G92 performance axle ratio (which also included dual catalytic converter exhaust, oil cooler and the J65 rear disc brakes).
