So I had a couple final things to finish before I drove it much more, or any harder. I had a slight coolant leak where the heater tube bolts into the lower intake. I kept taking it out and re-threading the fitting in a couple times but was always afraid it was getting cross threaded, but finally got it in there and snugged down as tight as I think it should be before I crack the lower intake. I used some RTV on the threads to try and help it seal. We'll see if it holds.
I checked the timing too since I had the dizzy out. It's set around 12 degrees so I left it there. I might run a tank of 89 octane through it to see if it responds any differently, but I doubt it will.
Since I'm still breaking in the clutch I didn't rip on it too hard, but I drove it fairly aggressively last night. It feels smoother and sounds better for sure. Hard to make a determination on a performance gain yet, which I guess means the gain isn't huge although I'm sure there are some.
