Thanks for the info guys. Wow, I didn't think these mods would add that much HP. So 100HP above the stock 3.3 rating? So I guess I've got close to 400HP at the crank?

So which of the mods adds the most HP?

The engine feels very strong above 4500 rpm. I just took it on an 800 mile road trip, after changing all the W3DPO spark plugs. Pricey suckers! Well, actually, I changed 9 of the 12. I can't tell yet just how much stuff I've got to remove to get to the 3 plugs on the left intake manifold.
