How do you like your 340s ?

I just got my 2009 Challenger SRT8 6.1 Hemi 6 speed, awsome car but I have more fun in my 71 scamp 340 4 speed 4:10 rear. Sounds crazy but something about it makes it worth all the work I put in it. But when I finish my 71 Demon 5.7 hemi I guess I will be totally confused.
