Engine swap 170 to 225

Hey guys, trying to get some info/tips if anyone else has done something similar, but i blew the engine on my 68 dart it currently has a 170 but all i can find to keep it a six is the 225. Does anyone have any tips or advice? I have a mechanic friend that mentioned to check to see if some of the accessories from the 170 re compatible as well as the engine mounting points, if anyone can help me out i would really appreciate it!
