dat u racing Posted June 3, 2009 Author Report Share Posted June 3, 2009 thanks great news!!! the automatic's (620) came with the 4.62. my crew members are running trucks in the none points races and that gear will stomp the fords and yota's I'am sure it will be a lot of fun to pit for them!!

datzenmike Posted June 3, 2009 Report Share Posted June 3, 2009 Only the '74 automatic had the 4.624 ratio. The 520/521 with the J13 motor had 4.875 and aluminum carrier I believe. Quote Link to comment
datzenmike Posted June 4, 2009 Report Share Posted June 4, 2009 Be sure to check that the drive shaft bolt pattern works. Some 720s used a larger pattern, maybe just the 4X4s, not sure, but check. Yes, but only the Z24i motor Hardbody had the H-190 rear end. Quote Link to comment
