For sale looking to remove and sell my 07 600 mod motor complete everthing comes out and goes with sale. This motor is super tight and strong very low hours, compression is equal. Have extra pistons bought for spares and some brand new belts to go with sale looking to see if i can get $4,200 for this monster. It does require 110 octane fuel. either looking for conventinal motor or possible 440 so if you have one of these let me know as well.
