Looking at swapping a few things on my truck and have some questions.
First, can I easily find a new top for my injection pump? I have the style without the adjustment screw for the zero boost fueling.
Second, I want the 120mph speedometer vs the 85mph that my 83 came with. How hard is it to swap it?
Third, would 2.5" or 3" exhaust be better for the 4d55? I have a shop that is going to mandrel bend everything. I won't be running a muffler, just a straight through resonator.
