79 R/T. 360 to replace 318…

Hey guys, just joined the forum and have always loved the aspen body style and how they are a totally underrated muscle car from mopar. Anyway I've got a 71' 360 block from a friend. It was rebuilt 10+ years ago with TRW hyper eutectic Pistons with the skirt coating and 1.88 "J" heads. It's never ran in a car but it was uncovered and all dirty. Now it's at home and apart in the basement. Block needs a good cleaning and I'll probably go with 2.02's. Thinking of a cam comparable to the mopar 450/455 . I had that cam in a 360 with 2.02 heads and these same pistons and was happy with it in a '72 Swinger. I've got the 360 oil pan and a new MP distributer kit that I was going to use on my 340 Duster but went with a fancy MSD. Also a Holley 670 street avenger. So that's the engine I'd like to put in a 79 R/T that's for sale nearby. It's a orange car, black interior. 318. Buckets-console.Don't know if it's a 727 but suspecting a 318 car would be a 904 trans with it. Would this car have 3.21 open diff?? I can get a 8 1/4 from buds '73 Dart sport, 3.55's. How hard would it be to fit it? Custom drive shaft? I've got Cop rims cause their way cool. Headers of course. Will the 318 radiator hold to a 9.5 compression 360? I'm thinking of the car running and driving with a valid vehicle safety for less than $5000. Thoughts?? Advice??
