Well Andy I am not selling off my kids to build it, even though there are six to choose from. I was looking at the 440 source 470 rotating assembly and trick flow heads to start so we are already at $4500 plus machine work .....and everything else. Truck is still for sale and so is the project Duster. Not in a hurry either. I am debating just dropping this motor in to drive the car while I put this together. I have another 400 core as well. I am just not well versed enough to get the components right from top to bottom.
