" From: Jesse <j2sax@xxxxxxxxx> " " " I am putting an 86 360 in my 73 Commando. When I sold " the original 304 out of the Commando, I did not have " time to keep the 3 hole balancer that came on it. " " So, will the flywheel that came off the 304 with the " three bolt balancer be balanced OK with the 360 4 bolt " balancer? no. with one exception i know of ['70-1 360 & 390], each displacement has its own imbalance, thus its own flywheel. i'm not sure about the balancers but wouldn't be surprised to find likewise. i don't think the number of holes has anything to do with that, only the pulley set. " If it is just a matter of comparing part numbers, what " is the proper part number for a 360 flywheel that will " work with the 4 hole balancer? '70-1 360 p/n 3196929 '72-? 360 p/n 3212653 - i believe this fits all post-'72. there should be more detail in the archives... ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought _______________________________________________ AMC-List mailing list AMC-List@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list or go to http://www.amc-list.com
