K321aqs ?
 

Will this motor fit in my Cub 108 with a K241 in it now i know i have to get or build a wire harness but will it bolt in it came out of a 1450 cub so let me know and i know the K321aqs the a stands for special oil pan but whats so special about it is it because of the dipper on the rod is longer.Im hoping this will bolt in because i got one heck of a steal on this motor

It will bolt in as far as the bolt pattern on the oil pan.But,my guess is,if this K321AQS does not have balance gears,(most likely it won't)it will vibrate quite fiercely bolted directly to the frame.Keep in mind this engine was mounted with rubber iso mounts on the 1450.

It will vibrate no more than a 149 or 169.

149 and 169 had balance gears,right? Aqs 321 won't have balance gears right? The balance gears were put in to decrease vibration,right? So an engine without balance gears would vibrate more than an engine with balance gears,right? Or am I missing something?
