Hemi engine swap..is it worth it

Any of you guys that have commented on my post running a msd hemi 6 control box . If so what cam, intake and carb and you using. Are you happy with results and has tuning been hard or easy. Thanks
I have two of them. One is currently in a 73 Scamp, 5.7 Eagle with a 6.4 cam, Prefix/Arrow Cascar intake, 750DP carb. It runs well. Don't have any times with this combo. The other is a 6.1 based 426. Currently awaiting a new home. When it was in my 74 Swinger, it went low 10's. That cam is a Hughes 264/268 @ .050, 650ish lift, 1050 carb, Ritter 4150 Drag Pak intake.
