While its a great system I don't know if I would put it on something on purpose. I had a 91 mustang with a heads cam and intake modded 5.0 in it. It ran 12.30s, got 17-18mpg and was a blast to drive. However it wouldn't always idle right and i could never track it down. Some days I could sit in stop and go traffic with the AC on and no problems, other days it would develop a surge or just die. It was a 5-speed as well so idle should have been even easier IMO.
It was dead reliable though it did always start and idle cold. I have to admit haveing a low 12 second daily driver that would start and idle when it was 5* outside was pretty cool. I miss that car, it could truley be driven anywhere in the country without a worry run some low 12s on the motor and drive it back home.
