i got one for a buick v6.im not sure how much more power i got because the old carb was junk.they don't tell you what compression to run,how much timing to run,or how to jet your carb.im sure if i knew how they set theirs up for max power,mine would be faster.i thought that since they call it a system,that they would give me some guidelines.i sent them an email requesting how to set it up,but they sent me a very short answer.
