Big Block/A-518

@Whitey, It is a lockup as all A-518 came out of the factory that way to the best of my knowledge. From what I've assed with it, it is a good trans and I plan to install it without rebuilding it and I want to try the stock lockup converter to see how it works. It appears to be an 11 inch verter just by looking at it. I did get a price on a rebuild locally from a good trans guy I've been dealing with for many years. His price is $1000. I'll probly never order a trans from an out of state company ever again, cuz I've done that twice and both times it was a disaster. I want to try it in its stock condition first and decide weather it needs any changes before I do anything to it. I'm pretty sure they were used behind the Cummins diesel too so based on that I'm assuming the verter is strong enough to handle the big block torque, which BTW should be about 500 lb.ft. Any nay sayers your comments are welcomed.
