Decided to put the new endoscope I just bought use. First thing I wanted to do was take a look at the pistons after 3 hard seasons. I heard a lot of people saying timing advanced with stinger and a 850 is too much. Piston wash looks pretty decent to me. wondering what our resident expert think? A little fat?

What's your oil ratio? Nothing wrong with being rich/fat. dont know the engine set up like if it is OEM and bored out or if the cylinders were resleeved with thicker sleeves but watch the transfers for cracking. I can only assume you turning/spinning it up tight. High rpms.
