Are the fans in series in our LT1 engines? Can I remove one of them and still have one working fan? I'm in the middle of doing a few things on the car and the engine isn't running so I'm hoping someone knows before I reinstall everything.

I found a Hayden slimline fan 16" in diameter that flows 1900 cfm (rated at 1600 cfm through a typical radiator as restriction). I haven't measured yet, but I think I could fit 2 of these side by side on the back of the radiator. I have no idea what my stock cooling fan flow rate is though. 1900 cfm sounds like a boat load of cfm, but I haven't taken a look at what our engine at work is using for fans. Time to do some benchmarking.

Anyone know our stock fan flow rates? Any greater for '96 possibly than '94?
