I am trying to be very realistic here. I understand the costs that are going to be involved. What you guys have to understand is that my first car and restoration was a chevy. So right now I'm learning the way of mopar from you guys and my dad. He has 516 heads on his 440 so i'm going to talk to him and his buddies and see what they can find for me. Just be patient with me, I want to build a motor the right way and a big block mopar isn't quite the same as a small block chevy. I'm sure that the 3:23 is a good gear but I can probably find a 3:55 no problem. Don't worry about money or effort cause this restoration will be done properly even if i have to sit there with a template and port the heads myself or stay up all night working.
Understood...It just seemed like from reading your posts that you thought that porting your heads and maybe a cam was all you needed to get 400 hp, which is simply not the case.
400hp is not hard. You need machine work like anything else. Porting helps, but the real issue here is milling the heads and block. By getting closed chambers you will have to mill less which is better overall for the whole combo.
To get 10:1 with just head work you would have to mill alot out of those heads. So much so that valvetrain geometry would become an issue actually. This is why closed chambers work so well to get compression up.
