The 351 is a tall deck 351 cleavland a 400 is a stroked tall deck 351cleavland. these engines have big valves but low compression heads. a set of flat top or pop up pistons and one will scream. Also have to change to a pre 73 351c timming set OR change to an edelbrock performaer cam/intake/roller timming chain and you will have about twise as much power as stock as the factory timming is retarded somthing like 13degrees.
