Yeah sorry, I edited my post. It's an Edelbrock 1903 795cfm Quad.

It may work fine on the ABF style Edelbrocks...just not on the Quad.


BTO has This setup for the carb. It has the bracket for the cable, and the correct adapter for the 1902/3/4/5/6 carbs. They also have installation instructions specifically for the 1903 series carbs...a bit pricey, maybe, but ya might call them, and see if they sell just the adapter by itself.

When I replaced my dash harness, I couldn't get into O/D.  You know I was thinking, "What the..."  I looked in all the electrical prints I could find, but the truth came out when I visited my Vette friendly mechanic, and he provided me with an electrical print of the entire O/D circuit for the 700R4 on the 82 Vette.  (He subscribes to a service that gives him more detail than a shop manual.)  What I had been missing was the O/D switch on the brake pedal.  It has to be shoved all the way in, so the switch is "closed" when the brake is completey released (foot off), passing +12V to the O/D solenoid, and so that whenever you step on the brake pedal, the switch is "open," so the circuit for the solenoid goes to O volts, and the solenoid drops out, allowing the lock up to disengage for deceleration.  Let me know if you want the print and I will e-mail it to you.  It isn't the best quality print, but it helped me.  The most important thing from it is to be sure that the switch (the other white switch on the brake pedal that looks just like the switch for your brake lights) is pushed in against the brake pedal arm. 82delight2007-12-03 19:48:15
