Thanks in advance for any help here. Im doing and engine swap in my 67 tempest. Im removing my 326 and installing a 400 from a 74 Lemans. The problem is my motor mounts will not fit on the new motor. Is there an adapter, or will the mounts for a 74 fit on my car? Please any help appreciated. Im new at the pontiacs and probably should have researched this before hand.

I have a '75 Firebird 400 in my '67 Tempest and just changed the motor mounts. I ordered the standard mounts and they fit fine. I can't tell you if a '76 is different or not ... I read something recently about this, I'll see if I can find it. [img]/infopop/emoticons/icon_smile.gif[/img]

If the block is a '76 you do not have the provisions for the early motor mount. Give Dick at IA a call. They make many different motor mount adapter that will work.

I also swapped engines in my 67 Tempest. I sitched from a 350 to a 400. The motor mounts were different, but the standard motor mounts from a local parts store fit the engine. However, I cannot get the driver's side header to sit flush b/c it hits the frame. Did you have a similar problem? What did I do wrong? Is it possible that I placed the motor mounts in the wrong position on the frame? Please help.

The car had a 350 in it when I bought it. The motor mounts did not match the 400 so I bought some motor mounts and installed them. Someone told me that the external dimensions on pontiac engines (326-400) are the same. If so, why doesn't the 400 engine fit as nice as the 350? Is it the placement of the engine, the headers, or something else?

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
