I have a six cylinder engine in the ventura right now. I'm looking at a 400ci engine, where could i get the right motor mounts? or could i use the mounts that the six already has?

You will need the frame-side mounts for a Pontiac V-8. The aftermarket mounts are not 100% right. They can likley be "massaged" to work. They are the same for the 68-74 Venturas and the 67-69 Firebirds.
For the motor side, the same rules apply (68-74 Venturas and the 67-69 Firebirds). If you are doing something with significant power, consider the Mity Mounts...they privide a solid connection for the drivers side mount, otherwise, stock mounts will work.

You can get the frame mounts from Tamraz Automotive parts. They usually have a couple of sets listed on ebay. Get the ones for the 67 to 69 Firebird.

"I have a six cylinder engine in the ventura right now. I'm looking at a 400ci engine, where could i get the right motor mounts? or could i use the mounts that the six already has?"
Guess I read it as he having a 400 engine and needs the mounts? He will need both the frame and the engine mounts for the V8 installation. |

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.
