Things to be aware of when swapping a 440 for a 383/318?

So I am still looking to buy a Charger and presently I am hoping to some day end up with a 440-6 in it. Many chargers out there are 318/383s that have a 440 dropped in (or ultimately that may be the direction that I end up going). Regardless, are there any issues that I should be aware of when buying a car that has had this conversion (or doing so in the future)? I understand the obvious, that the engine has lots more HP/TQ, so in general does that mean that I need to make sure that I have a particular transmission, rear end or Is this only an issue on 318 cars?

Trans is different from a 318 to a 440...different bolt pattern. Brakes will need to be upgraded. As will radiator....rear end will need to be upgraded if you have the weaker 8-1/4" style....upgrade to an 8-3/4" or Dana

The rest is obvious, accelerator cable, power steering brackets & alt brackets....exhaust will need to be better as well

Those are just the highlights...

So reading between the lines, if I were to get a 383 car then I wouldn't have to worry about the trans or rear end as they should be able to mate up and deal with the power.

Your referring to the 904 that is typically mated to the 318 yes?

Thanks

Yes, to both

From everything I have read on this forum you can get quite a lot out of a 383, just wish I had stroked mine when rebuilding it.

I don't doubt that and that is one of the things I am struggling with - the completely un-rational want/need/desire for a 440-6 because it's just plain cool.

Of course, I understand  And, You can get much more out of a 440 than 383, that can be stroked too........

 I have had faster 383's than 440's (at times) through the years.  IT MUST have been what was inside them.  
383 seem to have a higher max rpm's too. Anyway, I love the 440's too. They get the WOW factor. At a glance, they look the same though, and share everthing bolted on except the intake.
