I have to buy the parts as i get the $$ The heads (basically the whole top end) is around 6500.00.Then a decent 440 block and a new crank,rods pistons etc...another 5000 aprox.but then I dont have to modify the K frame and just about everything else fromm a 440 bolts on.This is more for show than anything but have been told yhou get quite a bit of power from it to.I just wanted to know if anyone has done this and what all mods they had to make under the hood to make it fit and what they used for headers.i know you can buy the crate 426 hemis but you still need to track down the other parts....and as soon as the word mopar is mentioned the prices sky rocket even for junk.Damn I have given away everything from 4speed trannys to ramcharger hoods just to help someone out,Im guessing those days are a thing of the past.
