727 governor

For comparison sake, here is a late 70s big block station wagon weight disassembled next to an a&a 5400. There are many differences. I would say save yourself the aggravation and just buy the weight from a&a. Don't be afraid to go to 5600 or 5800, remember that you can fine tune the points downward a little be backing off on the tv linkage. The stock one is on the left.
