Weighing my options

I currently have a 1973 Dart with a 360 Auto. But was thinking about good 383 Big Block probality Auto. right back. But would my passing gear linkage still work, if i keep it? Would i need to change torsion bars I guess what i'm asking is if i was to make the switch what would i need or would it be better just to stay with the 360 and build it? I just like the ideal of a Big Block in a small car. I appreciate any help Thanks.

Why would you go through the hassle of putting a 383 in an a body to gain 20 or so cubic inches? I had 2 big block darts. I favor the big block but this seems like a waste of time and money to me.

If you go big block you'd best use a cable kickdown.

You do not need to change the torsion bars. You can even run /6 bars with a big block.

If you want to put a big block in your a body put a BIG BLOCK in it.
