shortly after the first of the year I am going to start searching for a converter company to build me a converter for my BB dart bracket car, engine has not been started so I have no clue what HP and torque figures this thing is going to make, besides the normal questions of what cam, what heads, what duration etc,etc,etc,is there any info that would be of help to get the converter as close to if not right on for what I need? I know that would be a stretch at best, or is just filling out the form and answering all the questions truthfully, as good as I can do to help these guy's out?
Secondly I have made a short list of companys that I think would do me a good job at a fair price,add to it and give me a reason why, Thank's
