Thanks for the guidance.. I saw next to the diagram it is 13-17 after final roll test..

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.

Awesome photos.. sensory overload. That Schmidts beer Camaro.. sponsored by Performance Engineering in Delmont, PA.. Delmont is next town over from me. The owner of that speed shop back in the day; Clarence E. Zahrobsky (Clem as he was known)  just passed away in April 2025 at 90 years old. He was the go to guy for high end race engines. Obit for Clem can be seen here..

I was under the car looking up above the axle near fuel tank and noticed this tab on the floor / trunk pan on passenger side. Any idea what this would be for? Looks factory to me but nothing is attached to it.. Car has chambered on in now.. maybe it was anchor point for different type RPO exhaust?

Is there a way to send a photo via PM?

Thank you Sauron327. That helps alot. I searched forum and never came across that post. I ordered the USA made one from HBC earlier in the day as Im just going to replace them both. I did send you a PM with another question or 2..

Was installing the parking brake retainer brackets on the previously installed shock plates. PO never installed the parking brake brackets. Passenger side went on no problem. Drivers side.. well the rolled lip of the shock plate is too high so cable bracket doesnt sit flush. Getting confused on orientation of the plate to determine if the PO put a passenger side shock plate on the drivers side. Is that even possible? 

Yea.. the X77 I posted looks like it might be legit but Im not an expert by any means

This one is on FBm NY as well

Reviving old thread.. On a 06A Camaro 396 right now. pump has the large AC on both sides of housing. CM40727 doesnt seem to line up with the table Kurt posted on CRG. Any input would be appreciated.

Endura bumper to boot.. with vinyl roof. Prob not many Z's in Butternut with those 2 RPO's.

I usually post the pic and location of the ones I list in orphans section. Dont know what haapened here.. Sorry

Thank guys. I think the 977 would be correct for my appliction but may have to do repop due to availability. PO just used the spacer variety that has no butterfly.
