Monza- TH 200 to TH 350 swap

I am swapping the TH 200 in my 1977 Monza 2+2 for
a TH 350. Does anyone know if the TH 200 tailshaft
that holds the torque arm in place will swap over to
the TH350? Also, are the mounting brackets for the
transmissions the same? Thanks to all who reply. mrmonza

I'm not sure if they'll bolt up right. If your
TH350 is from an F body or an H body then you'll have
no problem, except maybe light fabrication work. If
it's a standard TH350 with vertical mounting holes
then you'll have to contact Trans-dapt. They have a
bracket that allows "regular" TH350s, TH400s and TH375s
to bolt into F Bodies. Perhaps the bracket will work
with an H body as well. The torque arms are very
similar form the F bodies to the H bodies.

the tailhousing from your th-200 won`t
fit
becasue it`s a part of the trans case(not removable)

the cross member will line whit the new trans
to
mount the torque arm the best way is to have a h body
tailhousing
try Ken ( mahoy78spyder@yahoo.com )
i think he
has one
your driveshaft will fit
and your
torque arm shouldn`t need mods

Monza- TH 200 to TH 350 swap

What engine did the car come with?

I did
this swap with my 4 cylinder Monza (with TH200) to a
V8 with TH350. First, as Denis said, you can't swap
the tailhousing because it's not a separate piece on
the TH200.

If you have an F-body TH350, the
torque arm bracket will have a wavy-looking rubber
sandwich, which works with 4-cylinder Monza torque arms.
The 8-cylinder Monza torque arm uses a round
bushing
that is different and uses a different
bracket.
Unfortunately you can't "just" use a 4-cyl torque arm--you'll
have to shorten it 3.5 inches.

If your TH350
has no torque arm mount, another option is B&M's kit
that allows mounting a TH350 in an F-body. This is
what I have. Unfortunately this just puts you back in
the above situation--the mount is the wrong kind for
the V8 torque arm. I just kept my 4-cyl torque arm
and shortened it.

I know there's got to be a
better way to do this, but I just wanted to relay my
experiences.
