I am having a hard time deciding which motor to go with. I am putting it  in a 83 stepside Dodge pickup. So being original is not a big deal. I like the stroked 400. Just to try it. I have a 440 in my 66 Fury lll and also like that. The money for any of the three is close. Help  

I would suggest you go with what you like, a big block. The 400 is a great package when you use the stroker kit, and the torque will help liven up the pickup.
