Edelbrock Carb Vacuum Hookups
I just wanted to pass on a little info I came across after watching a dvd that came with my new Edelbrock Thunder Series carb. Now this may not apply to everyone, but it certainly helped my engine. This info pertains to the vacuum ports on the front and back of the carb. I have a 350 with an automatic tranny and I was always under the assumption that the transmission vacuum line attached to the port on the manifold just behind the rear of the carb base. Well according the Edelbrock the tranny vacuum hose goes to the drivers side port on the front of the carb and the vacuum for the distributor goes on the passenger side. I plugged the port in the manifold that used to provide vacuum to the tranny. The car has better throttle response off idle now and the tranny downshifts into passing gear more effectively now also. Like I said, everyone with an Edelbrock carb may not benefit from these changes, but I certainly did. Just a thought I felt I should pass on.
