Ebay Q-Jet, should I?

That's for sh*t sure. A stock carb has been methodically tested and optimized for that specific application by engineers with zillion dollar equipment at their disposal. . When you have the original equipment carb you just clean it- that's all. It can take a few motor modifications in stride and still operate well. It's when you get crazy that you need to start re-jetting and stuff, and that is usually not by much. Now consider a computer carb that is operating on commands from the ECM that has been programmed for all possible operating conditions. To replace that type carb the best you can do is find the model carb that came on the last non-computer version of your motor and hope for the best. Taking a totally different model and trying to adapt it can be so frustrating that you want to just grab an off-the-shelf-mail-order-whatever and be done with it. But you never are, because it will never be right. That is why Mr.Sony did the right thing. He found the correct model carb for his motor and will optimize it to work with the motor he built. THAT is the way to go.

Indeed. Holleys and Edelbrocks are designed to be plopped on in a few hours with minimal adjustments and run great. Quadrajets aren't designed for that purpose. People tend to shy away from them because compared to the other options, they can be more expensive and are more involving to diagnose and repair/tune. But when they work, BOY do they work. And if you rebuild one yourself and it works, you will NEVER go back.

MrSony I completely agree with you!
