68 Dart 440 Daily Driver Build Thoughts

Hey guys, pics of the build will come soon. i'm trying to document as much as possible. I have the block, 440, decked .006 down, .06 over, with forged crank, stock rods, balanced, forged pitons speed pro dished 7cc, all assembled so far. The cam I have is Comp cams energy .545 but i might change it out to maybe something a bit less depending. 1.5 rockers. I have a 727 with the 11.75" torque converter that i would like to use, not carved in stone. The heads i am looking at are the Edelbrock RPM 84cc to give me about 10:1-10.5:1 static compression. Schemacher Tri-Y headers are in the plan with 2.5" exhaust system exiting before the rear wheels. What my unknowns are: tire size. I need to put 15x12" rims back there to offset the cut rear end, steel cop car wheels and 15x8 up front, rear gears for sure depending on tire size, maybe different cam and torque converter. quad core rad with 2 electric fans. I think changing out the cam would be the easiest and least expensive thing to do if you guys think it might be too much for this type of application. Its not going to be a show car by any stretch of the imagination, just a fun thing to go here and there.
