Seems like a pretty small space.

The O2 sensor needs to be just after the junction of the header pipes. On my CR 1 it is located just before the muffler. But CR di make one mistake- they have it angling up instead of down. This will cause it to collect moisture and over time destroy the O2 sensor. But they did it to conceal it and fit it under the edge of the body. Still not right. But on a low use and fair weather car- not as critical.
I had looked at this same system for my car as well. The CR1 has the 5.0 mounted pretty high up in the engine compartment. As I was using a Kenne Bell supercharger- there was no way to fit it under the stock hood. But at a package price of about $2,500.00, I decided to modify the hood to clear the S/C. Since I already had the S/C which adds over 100hp, I modified the hood. But I thought the system was the best of the retrofit EFI systems that will give you the "original look" of a carb with the tuning of EFI. It does, as was mentioned here, have limits of performance to more highly modified motors without custom tuning.
The next best but considerably more expensive choice is the Weber style EFI systems. But at over $4k and much taller, it causes one pause.
