Pictures of Pontiac 400 engine
« on: January 21, 2010, 11:35:43 AM »
I am almost finished rebuilding the engine in my 78 TA with Pontiac 400 engine.  However, I forgot to mark down how the distributor (can't remember if the vacuum is to the drivers or passengers side), pulley brackets, and air condensor hooked up.  If someone could take a picture of these items, it would really help me to finish putting the engine back together.  Can't wait to have it started up and able to drive it again.

Thank you,

Rich

Vacuum canister on the distributer points to the drivers side.

I replaced the steel line with copper for the look . but here is an idea how it go's on . the vacuum line goes to the lower part of the carb so the distributor gets full vacuum.

Thank you everyone.  Your engines look great.  I like the copper tubes.  Might have to add that to my engine..

I believe your distributor is 180 degrees out of phase. the vacum advance should be pointing to the other side. Correct me if I am wrong.

It actually doesn't matter where the vacuum canister resides. As long as the fireing order is correct you can start on any post of the distributor. But most of the time that are pointed to the drivers side.

Virgil, what is that beside the EGR ? the silver thing with the vac line going to the front of the intake.
will I need one on my 77 or are all years different?

nope runs fine.  I have never seen one in the other way.   tried it once , but the vac line hit the intake when timing it. I see Virgil has his like mine.

That is part of the EGR system on my particular car, i have seen a few others with the same set up. Its been on the car since I purchased it. The vacuum line comes from the vaccum switch on the front of the intake to the diaphram and then to the EGR. The ones I have seen them on were manual trans cars.
