Need info on putting a Hemi in my 69 cuda

Well my buddy has a 67 383 Cuda and we decided that he wants my brother and I to build a Hemi to put in his 67 Cuda. We are checking on parts prices now. But we feel its worth it to just go and build the 528 Hemi as it really wont cost much more then the 426 build. So I will be looking into all the little details for this combo. He wants us to keep the 4-speed so I am looking into a hydraulic clutch setup also. I myself would go with the 426 style Hemi as the parts will be easier to get parts for then the old style Hemi. Ron
