'68 Dart with a 318 LA - Build Options

Thanks everybody for their input. At this point I'm just leaning towards a refresh of the 318 with very simple and inexpensive upgrades, a refresh of the existing 904 tranny, and maybe an upgrade of the rear end if I can find something affordable like an a-body 8-1/4. I'm getting ready to get the Dart up off the ground and leveled up for some front frame rail repairs so the engine and K-frame will likely be coming out soon. I'll find out then if a refresh of the 318 and the 904 is the best route to take. I'll definitely be doing a complete front suspension rebuild at that time too.
