74 Dart 318 replace with 86-88 318 any issues?
 

This is my first post, but have owned Mopars since 72. I have a 74 Dodge Dart sport w/318. I am planning on installing a new longblock reman. 318 w/roller rockers.

Any issues with bolting up to a 74 904 tranny? Can I use same motor mounts? I will be using an electric fuel pump.

Any suggestions would be appreciated.
