I just put an Edelbrock 1405 600cfm with electric choke and vacuum secondaries onto my 70 Chevelle with a 307 and 2pd powerglide. My question is this is there a way to tune th e carb so that the secondaries open up later than they do now. The car is a daily driver, so I need to see a little better mileage, tho that's not why I have the car. Right now they seem to open up at about 1/4 throttle. I'd like to see them open up around 1/2 half throttle. Any suggestions?
Thanks in advance!
Fred
