I already have an 03 5.7 truck engine, harness, and ram computer but can not figure out how to make it affordable. Still would not have any quench without spending a butt load more money. Also I have seen so many powdered metal rods break I am scared to run anything with them in it (remember whatever I do I want a rocking engine when I am done so all the rotating stuff will need upgraded). Those broken rods are how I ended up with everything to build a motor.

Highway mileage with my '79 300 with E-58 engine,factory duals,TQ carb, non-lockup 727, 235-75-15 tires and 3:55 SureGrip was 14.7 on a trip to Myrtle Beach last August, trying to stay close to 65 when possible. The air conditioning was running the whole trip. City driving nets about 10 mpg.Engine is running Mopar electronic ignition and a '70 340 camshaft. Current miles on the engine is 224,456.
