Edelbrock Carb Question
I replaced my Holly with an Edelbrock 4106 on my '75 and now I need to "tweak" it some. It really runs great but when I stomp on it I notice there is definately a difference in the shift duration compared to the Holly. The Edlebrock takes longer to shift than what the Holly did. Is there a link somewhere with documentation on tuning/adjusting the carb for peak performance? The reason I switched to the Edelbrock was I could not get the Holly to stop "perculating" the fuel in the bowls after I shut it down. Even with the heat shield I still had problems. I am running a rebuilt 350 .030 over with a comp xe 268 cam and a TH400 transmission.
Thanks,
Ron

If the detent cable is to titght it will hold the shift longer and will kick down to early.

the electric switch would only be if it has a turbo 400 auto trans. The turbo 350 uses a cable attached to the throttle linkage.

:iagree: with Paul
The TH400 had a vacuum line from the intake to the modulator valve and a orange wire that went to the kick-down solenoid (down shifting) activated by a switch on the accelerator pedal when fully depressed. Most up-shift problems are caused by a vacuum leak so check for that.

Re: Edelbrock Carb Question (redwingvette)
Thanks everyone. I don't know why I didn't think about the switch. It is located under the gas peddle. I think I recall that to reset it I need to press the accelerator all the way to the floor to (engine off :D ). I will also look to see if there is a vacuum leak to see if that may be the problem.
