Miles Posted June 2, 2009 Share Posted June 2, 2009 I just finished installing a SBC 350 in my 240Z. It is consuming gas such that a 18 mile round trip to work used about 1/2 tanks of gas. Data: Engine: GM Goodwrench 350/290 HP crate engine Cam: .450"/.460 lift, 222deg/222deg duration Carb: Edelbrock 1406 performer electric choke Distributor: MSD HEI Timing: 8 deg TDC Temp: runs about 185 deg using JTR radiator and electric fan Transmission: Camaro T5 rebuilt Differential: R200 3.54 Fuel pump: Edelbrock EDL-1791 Fuel pressure: 6 psi Idles ragged Off idle throttle is a little slow. Driving around town the fuel gage goes down fast. Any ideas. Thanks Miles Quote Link to comment Share on other sites More sharing options...
randy 77zt Posted August 14, 2009 Share Posted August 14, 2009 is that fuel pressure recommended for that carb?check the float level-i have had it off on new carbs out of the box.is the cam timing correct if you changed the cam?is the timing pointer correct or did you change something from the motor.carb will probably have to be rejetted -try to find a wide band 02 set up for tuning.
