Put the Duster on the DYNO.

440 .030 with Ross pistons. Around 11.5 to 1. 452 heads with 2.14 valves some porting. Mopar 312/.590 cam. M1 intake with 1050 dominator. 727 with turbo-action 3800 converter. 8-3/4 with 4.10 gear. All in a 74 Duster. Was told it weighed 2450 when I bought it. I think its a little heavier than that.
