The 400 would be nasty with a 4 inch stroke in it huh? Hmmm, I hadn't thought about going the other way with the 400 and ADDING displacement. That's definitely something to think about. If i wanted to get stupid with this motor I could do forged 4 inch stroke crank, forged flat tops, forged rods, a big nasty flat tappet camshaft... Hmmmm! We'll see, I have a little while to think about it because I'm going to spend the summer saving my money and slowly getting the car ready for a new motor. This way once I've saved all summer long I'll have a good financial starting point. I apologize if anyone feels that I've wasted their time talking about this, but sometimes you need to talk about something to understand why it is a good idea or a bad idea. Thanks
