change 318 to 360

I presently have a 1973 Dodge Dart Sport with 318 and 3 speed Auto
I would prefer to find a crate 318 engine from Mopar but it doesn't seem to be available.
Does anyone know of a new crate engine available and if so where? If not will the crate 360 work okay (hold up) with my present transmission and stock rear. Will I have to change motor mounts and what happens with the exaulst headers.
I would settle for a rebuilt engine but the new Mopar engine just appeals to me much more. Any suggestions on rebuilders will also be helpful.
Thanks,
Richard

How did the 360 work on some of your applications?

I think you have a 8 1/4" rear axle, which probably won't grenade with the mild 360 (the 380 hp one may be another story). Transmission will probably be OK too, although you can swap in A-999 internals for a tougher setup.

Here's what needs to be changed:

Motor mounts. Well, you only need to replace one, but these things do wear out after 30 years.
Transmission flexplate. The later Magnums have a slightly different one.

The exhaust and most other parts stay the same.
