HELP!!! 10.5 :1 Pistons
Posted: Wed Jun 25, 2025 11:28 am
Hello All! Newbie here, excited to be part of the Toro family!
Early production 1967 Toro deluxe. 84K miles, 1st time bottom end has been opened.
My motor is getting a complete overhaul, balance, blueprint etc. Time to order pistons, nut I cant find any 10.5:1. Every call I've made I find myself explaining 66-67 Toro 425's had 10.5 to 1 compression ratio, which I find the person on the other end of the phone doesn't agree.
Can anyone point me in the direction to find some pistons? and a new flexplate. The ring gear is starting to show some signs of wear.
