On modified vehicles you are the engineer. You will need to do your won tuning and write your own specs. In particular if you are running a performance cam and have greatly diminished vacuum, stock parameters are not likely going to work.
Bill Basore, just come tune my Cleveland please!!!
Where do you live? I like tuning. It is a really fine balance that you are looking for between timing, mixture, and gasoline. One thing that I always like to say repeat, is that most carb problems are actually ignition related.
