Help me find the umph in my 360

Dusty,
Post #89. Great results & on the right track:
- Irid plugs are good, as long as the correct heat range. NGK 5 heat range.
- 26* at idle & wanting more. Not surprised. Give it more if it wants more. Cut back the centri curve. You can also use vac adv connected to manifold vac [ MVA] to add idle timing. Adding idle timing helps the engine run cooler, & helps tip in response. Engine I tuned last Sunday liked 45*. A most misunderstood topic.
- spluttering under load could be too much timing, fuel related, lifter pump up or poor ign. If you use another coil [ like MSD ], check to see if a bal res is needed with it & make sure you use THAT bal res. Coil & BR need to be matched.
