I considered FAST when I installed mine however they did not support timing control at the time so I went with the MSD Atomic setup. Most of the systems offered now are basically the same so there is a good choice to select from and are pretty easy to install. That's the easy part, tuning can be a little more complicated than they make it seem on the videos. Once you figure that out and dial in the motor there is a world of difference in drive-ability and you won't want to go back to a carb. These systems are generally not recommended it you have a cam with a duration greater than 250* at .050". They don't readily mention that fact and makes drive ability unacceptable if you have a cam like this.
