I really need to get this crappy Holley carb off my truck and go back to the Rochester Quadrajet. Except I've run into a problem, it won't fit on my current manifold because I have vortec heads so I have the weird bolt pattern. I don't really want to run the adapter plate to fit the quadrajet so as long as I'm under the hood I figure I'd look to get some more out of the motor and get a new manifold too. It's going on a slightly built 350 thats mostly a DD but still sees alot of mud and desert. I'd like to keep the torque and horsepower ranges about where they are. It's got some good low end grunt but can still go down the highway at 80. I'm not worried about gas mileage. Ok so where should I start looking? and what types/companies/styles should I be looking at?
