No he will not need the car, he can do it of the the car and it will be right. He builds his own carbs that work better than anything you can buy over the counter. I've watched him test and get a couple of tenths out of the right carb. He has a high dollar Barry Grant that sits in the box because he can make an old holley run better. I can check with him to make sure but I'm sure he can help. If youwant send me an email and I will get back to you, dont think I will get him to do anything on a computer LOL.
