Need info on putting a Hemi in my 69 cuda

Thanks for welcome and the input. You're right the 451 engine is a great power plant. I take my car to lots of car shows during the summer and was looking for something you don't see around here to much. Namely a hemi under the hood. But being used to the 451, i didn't want to go through all the hassle of putting one of these hemi's in my car and have no get up and go. So i thought i would pick all your brains a little bit and see what would be the easiest and cheaper way to get the best worlds. Jeff
