March 7, 2010 - Since the exhaust was off the menu for the day, I turned my attention to the radiator.
It really is a monster. I chopped out more of the sheetmetal in the nose and tested to see how high I could put the rad with the hood closed. Had I specified the rad without a filler cap, it would have been a bit higher. Naturally the rad is just wide enough to cause interference with the structure of the hood.
Still, it's not quite as bad as this picture makes it look - which is pretty bad. At this height, the bottom of the radiator is approximately an inch below the front bodywork and about the same distance above the steering crossmember behind it - these are eyeball measurements, I haven't confirmed the exact dimensions. It has 6" of ground clearance. If I decide to install the MG Special Tuning airdam I picked up last spring, the radiator tucks in nicely behind. So we'll call that good then.
Due to the size of the engine and my decision to use (very slim) electric fans behind it, I have the radiator sitting quite far forward. If I were to put the fans in front of the radiator, I could move the whole thing back and gain myself some more clearance. This would make the fans less effective, but it's worth considering. After all, I think I have a slightly over-specified cooling system at the moment...
