Back in the day the 4x4 magazines did numerous write up's on the various kits for the 6.2

The power levels were actually slightly better than the GM factory stuff offered in 1992-->

I owned a 1991 Burb with a Banks kit and it was a sweet heart

Power levels on these are never going to be anything close to to a DMAX, but are very nice compared to the stock N/A engine.

I would love to scare up another 91 Burb with a turbo
