I have an engine tech 770 big bore motor that I am looking to sell. I am selling everything with the motor. That includes engine, Carbs, Pipes, and electrical. I will consider selling the top end and bottom end seperatly. The top end will bolt right on to a 600-700 polaris big block (non-VES) motors. I have 2 sets of heads 12-1 and 14-1 with the billet cover. The pipes are Crank Shop 770 high altitude twins. I am asking $1200 for everything. This is a great way to add some zip to a 98-2000 6-700 polaris for cheep.
