I ran engbldrs 268 cam in my 22RE and it gave me a bit more power to get up to speed (bottom end) but didn't really seem to make much difference at highway speed. I sold the truck and have an 89 extra cab with the 22RE now and I just had the exaust done from the cat back with 2.25" to a 40 series flowmaster, and I noticed that I now have about the same amount of power as the cam gave me on my 94 with stock exaust. I personally would get a cam with bigger lift because the 268 is so close to stock.
