In my 68 AMX I have the original M12 trany and in my 70 Jav. I have a 727 and I am wondering what the differnce in the gear ratio between the two is. My AMX has a rebuilt 390 putting out 380 hp and 470 trq. My Javelin has a rebuilt 360 putting out 325 hp and 380 trq. They both have twin grip rear ends with 315 gears and in the Javelin I could burn the tires off of it but with the AMX sometimes it kind of bogs down and wont even break them loose. I am wondering if it could have anything to do with the trany. _______________________________________________ AMC-list mailing list AMC-list@xxxxxxxxxxxx http://list.amc-list.com/listinfo.cgi/amc-list-amc-list.com
