This is pretty interesting that you guys are curious about an old 4.8L with minor bolt-ons.
Maybe I should start posting some of the dyno runs we do with before and after light mods.
Hell, everyone posts about their big bad numbers, but I guess 9 of 10 truck owners bolt on light mods and would like to know HP results.

The bays are still tied up, which is good, we're busy, but as soon as we get one free, we'll dyno this lil 4.8.
