Title: Exhaust Flange Torque
Post by: boomer632 on December 08, 2025, 12:33:28 PM
Does anyone know what the torque value is for the exhaust flange nuts for BB car with stock manifolds? Installing a new system and would like proper value for the stud nuts.

Is it not shown in the AIM? Either way, adding a little anti seize to the studs will go a long way to prevent the nuts from rusting on permanently. I would check and re-torque after a few cycles or 200 miles. Sometimes things happen
New exhaust system?

Yes sir.. Gardner chambered.
I am guessing you liked the audio clip I sent? Pretty stoked myself. Alot of fiddling and adjusting but I got the tail pipes within 3/4 of an inch of each other. Ill fix that in spring after a few heat cycles.
