372or 416 and why

I run a 372 in my 73 Dart Sport dynoed(452hp)440ftlbs. x heads port and polished with beehive springs and a comp xe284h cam.Great street/strip ran 12.8 at 108..Room for improvement.If you,ve got the money a bigger stroke say..408,416 will get you more hp up over 500hp.I didn,t want to have to put a cage in my car and with the bigger stroke I would have to add strength to the chassis,already tied and slide a link.Car is a 4 speed and hooks hard.At the time of build money was tight.Good Luck with your choice,either way it,s gonna be fast and you,ll have to beef up suspension and rearend.Have fun with your build!!
