Concur with JonJay. Fitting the sides/backs (minus the oil cooler) doesn't take very long, couple hours max, but the killer is the front ramps, air inlet (for FI), and the oil cooler. Those three are probably 95% of the big time consumers.
Tbone, do you have your engine yet? do you have all the fittings/ prop governor installed? Is your firewall prepped as far as you can go?
I'm still wrapping up the engine install, but in general, the basic flow was prep and hang engine, install cowl (including oil door), then baffles, then engine wiring.
