I first want to thank all of you for the responses. I should be a little more detailed. I am putting this 400 block in the car. It is a 1969 block i am not sure what it came out of. I can't find anymore numbers on the block except for the date code. It does have a D N on it but nothing i have researched told me what that was. I am going to build this engine on a somewhat budget. I am trying to find some heads that will work good on pump gas and ok performance. I will reconsider the goal if i have to do frame and body mods to handle it. I guess i am just looking foward to getting it back on the road.
Again thanks for you help and any other suggestions.
