572 Hemi / Is it Worth it?

IMO the only reason to do that would be to say "I've got a hemi".

There are many other ways to make that horsepower. Most of them are easier to work on and all of them are cheaper.

LX is correct but then when your finished you just have another 69 Dart. Cool in it's own right but still......... HemiDenny is a member here and he makes k-frames for this kind of install. You don't have to hammer the inner fenders or change anything. If you want to go back to a 440, 340 just swap out the k-frame for your old one, its that easy. Send him a PM
