Title: Motor mount bolts
Post by: sreta on March 04, 2024, 07:30:57 AM

Hi guys ! Does anyone know the torque specs for these bolts ?

Simply says Engine mount to block 75ft lb.
Engine mount to frame mount 50ft lb.

And that probably doesn't refer to the F-body type. I'll have a dig around later.

Sorry, forgot. But not sure where to look either. The Olds in Firebird specific brackets and mounts are rarely shown in anything available in print, avoided in the parts manual listing and none of the assembly manuals are for the 77-79 years. Just have to go off what is similar.
