We have the following:
73 c-4 tranny (uses smaller 157 tooth flexplate)
78 Lincoln 302 (uses larger 164 tooth flexplate)
We bought a new 164 tooth bell housing. We bought a new b&m o.e. replacement 164 tooth flexplate. The flexplate wont fit the torque converter -bolts dont line up. We think we received the wrong flexplate from Jegs-an AOD not 78. So, we go to the b&m site to see if we can match the part numbers. Well, the part number on the flexplate we received doesn't match the ones listed, HOWEVER-we found something interesting.
The 78 302 and the 73 302 use the same weight, just different sized flexplates (157 vs 164). Why cant we use the 73 flexplate, bell & starter on the 78 motor? I thought the issue with different flexplates was balance-weight. Here's a link to the b&m site: http://www.bmracing.com/products/trans_flex/flexplate_ford.html .
Anyone know if we can use the 73 stuff? Otherwise, we're going to need to get a new torque converter. And we havent even heard this motor run yet-the last thing I want to do is spend more money on it!!
