Guest Fummins Posted February 25, 2015 Share Posted February 25, 2015 Hi, looking to find some carb/performance tuning information. Specifically for my stock 1964 383 4bbl/manual trans Dodge 440. The Carter AFB carb was rebuilt by the previois owner and I feel theres some more performance to be squuezed out lol. Any data on tuning and tweeking the motor/carb combo would be appreciated. Thanks!! Link to comment Share on other sites More sharing options...
keiser31 Posted February 25, 2015 Share Posted February 25, 2015 (edited) There are MoPar street performance books out there and I suggest getting this book.... Edited February 25, 2015 by keiser31 (see edit history) Link to comment Share on other sites More sharing options...
carbking Posted February 26, 2015 Share Posted February 26, 2015 The AFB's were pretty well suited to the stock engine.I believe better sources would be the original Carter specification sheets, and the original MoPar service manuals.I have had a lot more AFB's come into the shop that were "tuned DOWN" rather than "tuned up".Unless you have seriously modified the engine, build the carb stock if you can buy gasoline. If you have to use E-10, a couple of minor tweaks may be in order, but build the carb stock first so you have a repeatable baseline. Then you know what your tweaks actually do (or don't).If you REALLY want more performance, change the manifold, and put a Carter TQ on the engine (DON'T do it with a manifold adapter).Jon.
