    451 build 1975 dart

    Hi. Im new on the site and looks like it could be extremely helpful to me. I have a project on the go with my 75 dart. It had a 6cyl in it but now has a 360 that fit just fine. But i would like to fit the old farm trucks 400 thats been sitting around for a while put some 440 parts in it. There seems to be alot of options i can go to help it fit, Could anyone be kind enough to give me a low down on what i am expecting. I am also looking into an A833 4 speed, the tranny in it now is the 3 spd auto. I already know about the machining of the bellhousing and the floor will have to be cut for the tran itself.Is the 75 a good year to do this build? Can i keep power steering? what would be the best heads for a street/occasonal drag car and do some heads move the headers into something they shouldnt hit? Im just a back yard guy that thinks he can handle this, so if i could get as much info as possibhle that would be great and much appreciated. Great site by the way

    im kicking the idea around about a 451 build. you really need to look at the total cost. i think you can do a 440source 500" stroker for the same price, getting 50 extra cubes. you can save money using ly rods on the 451, but they are still just stock rods. 440source has a price listed on their site, but im not sure if its a base price or if it is a one price fits all kinds of deal. i dont really need a 500" hell for what i want to do i could get away with a 400 rebuild, but a good piston for the 400 isnt cheap.

    I just found a set for 400 bucks, that almost sounds to cheap, KB 280's, it says set of eight, Im thinking this would be reasoanable or am i wrong.
