Quote: I HAVE A 71 440 BLOCK IN THE CAR NOW I WANT A DATE CODED 440 SIX PACK BLOCK TO PUT IN TO A 70 CHALLENGER THAT IS A TRUE V CODE CAR
All you need is an F440 HP or HP2 with the date code you think is correct. you could even goes as far as getting one with a VIN that is from the same plant that your car was built. there is absolutely no difference between a 440 non hp block , HP block or HP2 block other than the stamps ... and the PRICE ...
