Brad,I tend to agree that the later stands were all
the same,,except for the 307 stands. Why those were different,I have no
clue.

Larry,
No
problem. Also, my info is for '66-'67 engine mounts/frame stands/or
whatever they are really called. My car is an SS396 so it had the old
big block stands. When I had trouble with the headers I put in the small
block stands and that cleared up the issue. Since the big block is
bigger, they did their best to get it to sit lower in the car. After
'67, I guess they just made the hoods taller and simplified with one mount for
350 and big blocks. I have no idea why they did anything like they did
for the 307 cars...

Thanks Brad. I'm hoping you'll understand when
I tell you I hope your situation is different from mine, considering what
Clint said about different mounts for small blocks.

Mount Question
Larry,
I
think you have it backwards. The big block mounts lower the
engine. I had a small block with big block mounts and had lots of
trouble with headers. I swapped to small block mounts (sold the big
block mounts to a buddy) and the engine is raised up just enough to make
headers fit.

When I installed my big block, I had to buy
a set up upper engine mounts. I bought a big block set, then discovered
that the ones I got did not couple correctly with the chassis mounts.
The upper mounts were too big. I tool one of the chassis mounts off and
took it to a local parts store. We discovered the engine mounts that fit
my chassis mount was identified to fit a 327. I guess the previous owner
must have installed a small block at one time or another. Remembering a
thread on the list where people said both will work, except the engine
would sit a bit lower with the small block mounts, I bought a set of
small block engine mounts and installed the engine.
I have since discovered I need the
engine to sit 1/2 to 1 inch higher to address my header clearance
issues. I'm assuming if you set the SB and BB chassis mounts down side
by side, the "hump" where the engine mount couples with the chassis
mount would be larger and taller, raising the engine a bit?
I appreciate your comments,
Larry
