That is kinda what I figured. Any small 4 bbl that would work good on a 283 Chevy or a 289-302 ford would be good for a 302 GMC. I know that in the past I have been guilty of putting too big a carburator on whatever I was running at the time, with all the bad manners that go with that kind of desion. I went to a pretty big swap meet today, unfortunately no WCFB carbs for sale. Not trying to hijack the thread, but how about a 2bbl instead? If a good balance could be had between size and low speed air volicity that might work also. Just a thought. Jay
