As long as the carb port >supplies manifold vacuum you're OK. It's one near the top of the carb...I'm gonna move it today. > As for the pinging, >have you checked the timing and for vacuum leaks?

When the vacuum leak was fixed the other two barrels opened right away. >If you're interested there's a '73-87 Chevy/GMC truck >list/group at groups.yahoo.com. It's fairly low-traffic >but there are knowledgeable people there. Thanks Brad, I'm signed up and will introduce myself when the pics get fixed...thanks for the info.....
