Slant 6 to 318 swap, 72 Duster, Using 75 D100

Car looks decent..chk #'s on the heads and chk driverside of the block to see if its really a 340,does it have all the pieces such as exhausts,steering column,title,driveline etc? also chk vin to see if it was a real 340 car or what...if its a real 340 car try to get it as cheap as you can and build it...with your duster as the donor...just a thought..what rearend is in it?hopefully an 8 3/4 or at least an 8 1/4 bigbolt pattern...keep digging your getting closer
