Hello my name is mike. I am new to the mopar world and having a good time so far. I bought a 73 duster that is a 71 demon clone. From what I can see its a 360 car with a set of eddy rpm heads. It runs good I drove from enid ok to Miami ok then to mokan dragway and raced all on the same day (2.73 gear and a 24 inch tall tire got about 16mpg on the 780 mile weekend). Went 13.71 at 101 with the rockers loose and a 500 cfm edelbrock carb. then drove it home at the end of the weekend. Since then I have added a explorer 8.8 set of 6.5 backspaced race stars and some 28x10.5 et streets. then I got a tachometer a new 110gph fuel pump and fuel pressure gauge. last trip to the track with parts added managed to go 13.8 at 94 but collapsed a lifter I think. So waiting on funds to get new cam and lifters and what ever else it needs to make it run good again.:hello2:
