You should have the 350-454 frame mounts,Rick. Your
problem almost certainly was caused from the new motor mounts you
bought.

Any guesstimations on what I have in my
72? It was an original 350. When I first
installed Headers ( Thorley Tri-Ys) they fit fine. When I
installed a crate 350 I bought replacement mounts at a parts store. At
that point, the headers rubbed on the lower portion of the steering shaft.
I had to put several washers between the mount and motor on the drivers
side to get the necessary clearance. Til now I never knew that
there was a difference in mounts. If I'd bought the 307 mounts would they,
combined with the 350 towers, cause clearance problems with
the steering column? Interesting & enlightening
thread.

Right
Clint, 2 sets as you describe. Seems like The General could've saved
a few dollars in production costs and just used the same mounts. :-)

I'm pretty sure there are two frame stands for 68-72,,307 and 350 & up. I
think the frame stands on my 68 were 307's because the car originally came
with that engine. My uncle might have changed the stands out when he
installed the Goodwrench 350 it had when I purchased it. However,I didn't
have any header problems with the Hooker Comps. The car had an auto trans so
that might have made a difference,though.

I got this off a Google search - as usual, it does not put the matter to
rest...
THE Chevelle ONLINE INTERCHANGE MANUAL: CHASSIS SECTION
ENGINE MOUNTING (Chevrolet V8)
It is important that the frame mounts that secure the engine should match
the motor used, and this is important in which certain components like
header clearance and clutch linkage angles are maintained. The part
numbers
that I have listed for Chevrolet engines are discontinued by GM, but the
only way is to find a set that are either NOS or as a reproduction.
*There are two frame mounts that are common with the Chevelle, and the
Chevrolet part numbers cover both the 1964-67 and 1968-72 vehicles. P/N
3872815/3872816 fits 1964-67 Chevelles with big blocks, and the small
block
counterparts are P/N 3840715/3840716.
Not much is known about the mounting hardware, since the part #s were
abstracted from Super Chevy magazine.
*1968-72 frame mounts use two different mounts to mount the V8, and the
most
common mount that is used are P/N 3980711 and 3980712. 307-powered cars
used
frame mounts 3980707 and 3980708.
The 307 frame towers, P/Ns 3980707 and 3980708, are taller and wider than
the non-307 frame towers, P/Ns 3980711 and 3980712. The non-307 frame
towers locate the engine a 1/2" lower in the engine bay. The engine
cushions are specific to the frame mounts listed above.
The only completion of mounting a Chevrolet engine into any A-bodied car
will require the correct engine cushions, and aftermarket companies like
TRW
will manufacture the OEM style cushions, or the solid mounting hardware
available from Moroso will fit in place of the rubber cushions, but this
will wreak havoc on certain components like trannies and the driveshaft.

Engine mounts yes. Frame mounts, I don't know. I would suspect yes.
I went to autozone.com and put in a '72 chevelle big block, then a small
block. Both of the engine mounts are the same.

I didn't track all the emails in this chain, but the motor mounts for
a
BB
vs. SB in a '65 are identical in every shape and form. The frame
mounts
are the exact same height also, but the BB version have a small relief
for
clearance I suppose, but are completely unnecessary on my 502. I
don't
know if any other BB's needed this clearance, but I doubt it. So I
say
stick with the SB stuff. Its all the same.

If you run headers,they will hang a little bit lower.

Clint
would setting the engine lower vs. higher make any foreseeable
clearance
problems?
