Glad that's over with.
OK, now for some observations & questions:
1) Were the motor mounts assembled to the block prior to the BB painting process at Tonawanda?
Would there have been any orange over spray on these motor mounts ( see the original mounts at the beginning of this thread )?
2) Were the BB motor mounts 3920627 ( 3937930 ) used throughout the 1969 production year?
When were these mounts discontinued from production use? Why do these mounts have two different part numbers molded on them?
When was the left side stop bracket assembly discontinued from production? Did it make it into the 1970 model year?
3) When did the BB engine frame brackets 3980941 & 3980942 replace 3950113 & 3950114?
4) Using the AIM as a reference, no part number could be found for the right hand long motor mount bolt.
Extrapolating on the information I could find, it appears that possibly the standard 8 cylinder long motor mount bolt: 3980716 appears to be
the correct part number for use on the passenger side motor mount of the 302, 350, 396, and 427. See AIM – page 87. Can someone
reference a 1969 parts manual and tell me if I am correct in my assumption?
So sorry to all the Z/28 & L/48 guys here. Until I got into the research on this topic, I didn't know that the these cars used a similar
stop bracket. Odd that
a thru bolt and nut assembly was used on the Z & SS and the big block used the threaded receiver. Are there any Z/28 or L/48 owners here that can post images of
their motor mount components? I'd like to see them for comparison purposes.
OK - I welcome responses.
