I changed out the manifold yesterday to the new Performance Products polished manifold and when I removed the Q-Jet the inside of the manifold was soaked with gas. That finally helped me make up my mind to get a new carb. I've read all the carb posts and know that a lot of people like the Holley/Demon carbs but I've also read a lot about leaks on them. I also didn't want to go with a new Q-jet because in my experience they're just too finicky. I've read all of Lar's papers and realized I just don't want to get into a carb that much. I ended up ordering the new Edelbrock Thunder 650 CFM with electric choke. I like the idea of no gaskets below the fuel line and also the idea of being able to change things without having to open the carb up. The adjustable secondary valve will also be a plus. So, here's what I ordered.

Edelbrock Thunder Series AVS Carb
Edelbrock Heat Insulator Gasket
Edelbrock Fuel Line(the one that uses the banjo fitting and goes under the carb.)
Edelbrock In-Line Fuel Filter
Summit Adjustable Throttle Cable Bracket
Spectra 3/8 inch Stainless hose
Spectre 3/8 inchMagna-Clamps

Have I left anything out? The only thing I'm not sure of is whether the carb will clear the rear manifold fitting that feeds the headlamps and heater controls. I'm also not sure where the fitting for the power brake booster will go. I couldn't see a good picture of the rear of the Edelbrock so I don't know whether the tube will attach to the rear like it does with the Q-jet. Any help in these two areas will be appreciated. Wish me luck. :seeya

I'd drop by the local auto parts and get about 3' of each of the vacuum line hoses including the power brake line (3/8"?). Invariably some are too short, or dried out.

Also since you had the Q-Jet don't be surprised if some creative enginering is needed for the air cleaner and breather lines that connect to it.
Good luck and let us know how this new carb performs.

Thanks bigvette1. I think I'll be OK with the hoses. The PCV and vacuum line to the carb are about in the same place as the Q-Jet so I don't think they'll be a problem. I'm still not sure how I'm going to connect the EVAP hose from the cannister. I may be able to put it on a T with the PCV but I'll get it running first without this connection and then add the evap hose later after I have things dialed in.
