Hello all! Looking for a little help with the torsion bars that should be used in my '71 Charger. Was original 318 and now 440 and need to upgrade the bars to sute the current combo. Guess the question is what diameter are the big block bars supposed to be and what would be the number on them. Also would it be advisable/advantageous to go larger than the O.E.M. standard size and what should I look for? Always appreciate the help! Greg

The big block 440 bars are .092 in diameter, Stamped ID NO. 780/781
Your stock 318 bars are .088 in diameter, with a Stamped ID NO.776/777
There was also a seperate bar for the lighter 383 BB Witch was .090 in diameter, stamped with ID NO. 778/779
As for your question of what bar to go with, it will depend on the overall front end weight change your actually going to have.
With my Abody 440 swap from its original 318. Im still using the 318 bars.
The 318 was loaded, Air conditioning/Power steering/Power brakes/Emissions crap.
VS none of the above with just a 440 with aluminum heads /intake and battery in the trunk.
Depending on the total swap perameters maybe the current 318 bars will be fine.

Thanks again for ALL the replies I had the .880 bars in there so anything larger will be an improvement I'm looking @ going with the .960 Mopar Perf. bars unless there are issues with them quality wise. This is a 46,000 mile driver with the original rear springs in excellent shape. I don't want to over spring the front and plan to add a front sway bar for roll resistance in the future. No corner carving. Just looking for a good ride without plowing the front end turning a corner or getting on a highway ramp
