How about the basics rotor cap wires plugs?
If this is the 4.3 they have a plastic base that breaks on the distributor that causes the cap to wobble and misfire.I have seen guys zip tie their cap in place top to bottom as a elcheapo repair.
These era 4.3 and 5.7 gm engines were pretty particular on what tune up parts they liked.
I have had napa caps and car quest caps that misfired out of the box on the 4.3 and 5.7 gm/delco caps have been my best bet,I run a fleet of about 25 of these year trucks.
Good luck.

There are lots of different formulations and colors these days,your best bet is to stick with what you know is right for your car.is not a great idea to mix propylene with ethylene coolants,and that is easy to do these days when you just go by color and not formulation.
Good luck,cheers Jay.
