Ok the little "valiant" badge on the rear portion of front fenders was on all '70 dusters,as for the "V8" on the front portion of the fenders,i;ve owned 3 dusters 2 number matching 340 cars,and 1 318 car the only one that came with the V8 badge on the fender was the 318 car...as for compression '68-'71 340's had 10.5 to 1 ...

Thanks for clarifying on the V8 badge, makes sense now ... Also the 10.5:1 vs 10:1 ..I'm with ya so far, but I still believe they switched to the lower 8 or 8.5:1 engine during the '71 production year.. I'll never forget that '71 plum crazy Duster 340 (especially the soft motor) Once I destroyed that and installed the older 340 from the bone yard, MAN did that motor rip !!!
