2. Missfire/idle: You mentioned the water pump blew. Please tell me NO water of any kind got on your opti-spark. You might want to go ahead and pull the opti and at least remove the cap portion and make sure it is clean, dry, and corrosion free inside. If it is not a new unit, at least a cap and rotor kit would be a good idea.
I enjoyed watching the video. You are going to have a blast.

I'm not sure i understand that first question. I'm kinda clueless about the cooling system so far. We havn't bled the system yet but that is first thing i'm gonna try when i'm back in town for spring break. Then i'm going to make sure the little shaft that spins the water pump isn't damaged and is still there. I'm running the factory 69 radiator (hoses routed to the right side for pickup and return), i plugged the oil cooler port in the water pump, coolant line from the back of the heads t's into a heater hose.
As for the misfire at idle. It's pretty well solved for now. It runs actually pretty well, kinda hard to drive with no backpressure and afraid to make it to loud in my parents neighborhood. No water from the waterpump as far as i know has hit the opti, but i might open it up and check for corrosion. When it comes time to replace that i will be going with the coilpack Delteq system.
