Thanks chuckthetruck. I had tried to ID it by that number on google but it turned up nothing. I finally figured out just use the first 4 digits.
Scott, thanks for the suggestion. I have a Q-jet from my '83 Jimmy I forgot to take back for my core deposit in time. After seeing the price of an Edelbrock kit, I'm considering it. I don't suppose you know if it needs an adapter to fit an Edelbrock manifold, do you?
