If you want to run at an IHRA or NHRA, you can't have more than 6-12" of rubber line in your fuel system. At least that's what I'm told. Other than that, if you want some help on how to do the conversion neatly and nicely, go to
http://jason.fletcher.net and scroll down and find the conversion page. Its the best web page for it, and that's how I did my 86 conversion. If you need any help, let me know.
