So here is the story. I found the car on cl after a long search for a rust free mopar a body. 1973 duster. It was over a 100 miles from home and the pictures were vague at best. So I dig for as much information as possible.so the kid (young father) tells me him and his father worked in a Auto yard in the next state up.so they start with the pic of anything they need. They start at the slant 6 duster. grabs a 318 and 727 automatic out a 1983 Dodge diplomat police pursuit car,and a K frame out of a 68 Barracuda to put it on. lucked out and already had disc front breaks. I'm told before the motor went in they put new mains, rings (stock) , and a new mopar purple 284 D - 464 L cam. Said they tried x heads, but they were bad.so went with 360's.LDB4 intake, 1406 edelbrock. I was looking for rust free, I didn't even ckeck to see if the motor turned over! ! Took it home . pulled motor& transmission. Found complete 4 speed set up (so the ad said! Another story! !!) Got 8 1/4 rearend 355's, then sure grip. Put motor on stand. the numbers came out race engine or something like that so we took the pan of it did not have 4 bolt mains but it did have a windage tray. We put a new timing chain new water pump new fuel pump and resealed the motor. everything back together got it did Terrier and took off the bumpers. Found rims and tires from a 05 magnum? Cheaper than 14's?? Took off power steering , new headers, glass packs out side. Okay, last weekend at the local race track. Mind you all, this was the first time at the chrismas tree in my life! !! (That was like crack! I wanted more and more! !) 15.4 ? I was not finding traction til third gear. So last week I found some et slicks. And a couple of days ago my uncle and I have put on a dual quad tunnel ram! Started right up and ran like a bat out of hell! Especially when that second carb starts kicking in! but like stated I need to take it to the track to find the true time. would like to try it without the tires first and then after?
