THE BOOK I HAVE CLAIMS THAT A ( 1969 ) 4 BARREL CARBERATED 429 CAN HAVE 340 HORSE AND 480 FOOT POUNDS OF TORQUE JUST IN STOCK DRESS. SHORTER STROKE THEN THE 460 SO IT WILL ALLOW IT TO CLIMB THE RPM BAND FASTER. I LOVE THE OL FE MOTOR BUT AFTER TALKING TO PAUL KANE I AM REALLY IMPRESSED WITH THE POSSIBILITIES OF THE 429/460 MOTORS(1969) AND OLDER ANY WAYS IT ALL SOUNDS GOOD SCS
