budget street motor 360 or 383 for 71 duster

8 to 10 grand? I only had Close to 6500 in my 440 in my 73 dart. But I will say I bought the short block used. I payed 2800 for the 440 short block and around 3500 for the Indy ez heads. The 440 was built to run on 93 pump gas and my 73 dart weighed 3520 with me in it. The car ran 10.60 at 126 with the wrong torque converter. Just trying to say that you can build something pretty cheap if you can find deals on parts.
8 to 10 grand ? 6500 in your motor and the addition of ALL the other parts needed headers, intake, carb ,ignition the list goes on and I haven't got to the chassis yet. no matter how you slice it takes 8-10 grand .
