Chrysler 400 Vs. 440 into "A" Body

Hi All,

I have an oppourtunity to get a 78' 400 motor for real cheap $200. This is a running motor out of a NewYorker I believe. I wanted to ask the question how much easier is it to put a 400 into an A body VS. a 440? Also what machining is involved? I have a 440 steel crank which I need to grind anyways, and put it into the 400? Other than that I was going to use the factory rods out of the 400 and just replace the pistons, and heads to get my compression up to 9.5-10:1. I'm looking to make 450HP with the build but if it will cost a lot more to do the 400 I'll just stay with the 440. Your thoughts??
