thanks for the info. i cant take credit for the short block becasue i bought it used off a guy from moparts. he built it for his street 66 B-body and then decided to build a 500 for his car. i only payed 2800 for it and thought it was a great deal at the time.now the roller cam and heads i bought brand new from porter racing heads. well between the short block and the heads i have about 6200 in it. i did install the heads etc. the trans is a TF727 built by me with cope racing transmission parts. sorry i don't really remember what the rpm threw the traps were its been to long, but if i remember at the time i was shifting at 6500 when i had the 4.10 gears and i think my friend was shifting at around 6200. well if i ever get my back fixed( i have 4 herniated disc in my lower back, started getting spine shots and have one left. the doc said if they don't fix it i will probably have to get back surgery.) I hope to start swapping parts over from the dart to the duster. it is a all steel 73 duster that i put the front-end from a 72 on it. it does have fiberglass fenders though. when i get the money i am going to get a fiberglass hood and bumpers for it etc. I was thinking about using lexan for the windows but not sure if i want to go threw all the trouble of keeping them clean etc. i dont have a shop so my car sits out side all the time.here is a few picks of the dart. thanks Bobby also threw a few pics of the duster its the red car.
