Thanks guys! It certainly does move now. I would love to see how a pair of Vortec heads and a cam does on an engine like this, especially since the Vortec heads favor 32 degrees also. I bet it would be a pretty amazing combination.
I’ve always gone with Iridium just because it’s the best material available in a spark plug. It is longer lasting and has great anti-fouling capabilities. Ignition systems are a bit of a misnomer when it comes to performance gains - you’re not going to “gain” power in the sense of adding a cam, better set of heads, or turbo will, as examples - but you can restore lost power when compared to worn or low quality ignition components. Preventing a power loss (rather than creating a power gain) is the best way to put it.
I did a little more on the truck this weekend, and changed out the old shocks for some new gas charged units for a better ride and to give them more control.
