WOW...This sh!t is harder than I thought. There are so many ways to figure this out. Some times I think F/I is easier. I'm going to try this vac. idea this weekend. I'll let you all know how it worked. I would like to thank all of you for you help and advice. All my friends are Chevy guys and say just put a 750-850 carb on you will be fine. Maybe thats why they all smoke!!!
Thanks Again
