Howdy from Missouri

Hello everyone, I am new to this, I have a 1971 Dart Swinger, it is 90% restored with just a few small things left to do.
It has a stroked 318 in it ,with the 8 1/4 , 2.76 rearend still in it. I would like some input on either keeping this rearend and just lowering the gears or doing a swap !
Looking foward to any advice, I could use all the help I can get!
To be honest I have been a Ford man, but when You are talking muscle cars , its got to be Mopar!

Thanks
