springs, cam, rods, built trans, cal-tracs :cheeky:
Coils are fine, the truck coils are some of the best OEM ones IIRC
Spark plugs could stand to be a step of two colder too
Internals will hold for a while on a decent amount of boost
Depending on how crazy you want to get, I'd look into the following:
Tranny, rear end, fuel pump & lines, harder valve springs, boost friendly cam, etc.
