340 To 383

ANY ONE GOT GOOD ADVICE ON SWAPING A 383 INTO MY 73 340 DUSTER
PULLED THE MOTOR TO REBUILD IT (HAD A BENT PUSH ROD SO FIGURED I FRESHEN UP THE ENGINE) AND IT TURNES OUT THE MOTOR MOUNT ON DRIVERS SIDE OF BLOCK WAS BROKE AND ALIGNMENT DOWEL ND LOWER BOLT WAS BROKE OFF THE PASSENGER SIDE BLOCK. HAD THE CAR FOR 3 WEEKS AND NOW I'M JUST BUMMED, I GOT GIVEN A 383 AND THINKING OF SWAPING EVERYTHING OUT, ANY SUGGESTIONS OR INPUT WOULD BE GREAT. :sad1:
