    I received all my Breeze bits this week, and got my coolant system plumbed. I bought 3 gallons of premixed coolant, and threw it in the system, but I need more apparently, as the level hasn't reached the top of the manifold, where I removed the plug just in front of the water temp sensor. Thinking another gallon or so will probably do it. The lower radiator hose is a bit close to my serpentine belt, but I have a inch or so clearance, so that should be plenty. I routed the Breeze lower radiator hose kit above my power steering cooler, and just below the center of the front 2" X-brace; if that cooler wasn't there, the lower stainless tube could sit lower, and likely give me more clearance at the belt, but there's no room to lower the cooler. Should be okay. My Remflex header gaskets and ARP header studs should be here today, so I might bolt all those bits up this afternoon or tomorrow. My plug wires will be here Thursday, 3/13, so I might be attempting a first start next weekend. Already getting nervous/anxious, just thinking about it. I've built several engines over the years, and never had a failed first start (knock wood), but it always makes me so nervous, thinking about all fasteners that have to be right for it to a)not leak like a sieve, and b)not fail catastrophically. Hah! Oh well, part of the experience!

    Have a great weekend, everyone!
