I got a 440 with what i was told to be a 700 motor. I melted it down and there is no id on it accept for the casting. It says 923690 or 923691 im not sure. my guess is 0 though. Some one said its a 99 on here when I googled the #. But wiseco lists the 99 700 summit x as the 670 motor and the gt700 as a 699. there are other #s too "394/1 1" and "GILDARDONI 1/1" PLEASE HELP! Thanks.
