.85 is 318 car correct? Does that mean someone has changed the torsion bars from my orginal .87 or could it be that it came with .85 from the factory despite being a 340 car? Im pretty sure someone went through the suspension many years ago.
.85” bars were for 318 cars, yes. In fact, even the 318 cars with factory A/C came with the larger .87” bars.
So, if your car is a true 340 car it should have come with .87” bars. But mistakes definitely happened, and it’s very possible that sometime in the last 46 years someone could have swapped them out.
