mini-starter questions

My car needs a starter and I am planning headers so I know I want a mini-starter....

I seem to remember seeing a post a while back saying that the newer 318 engine starters were smaller.....

Or is the Mopar Performance mini starter the only way to go?

Any other info I need to know when buying the starter?

What do you guys think of this one:
