hopefully this is a quick and easy question, when i took my manifold to be cleaned i took everything off of it in a rush, and never took note of where each component went thinking it would be self explanatory.... wrong, seems like everything has the same thread and i dont know where to put the temp sending unit, the elbow, and one last thing i dont even know what it is, it the same thread as the temp sending unit, and had a steel line coming off of it into an elbow, i forgot what this went to....

 

pics would help a ton

 

yeah pics would be win.

 

...and engine size.

 

its a 289, all stock rebuilt, including intake, and i think exhaust mani as well?

 

oh my fault

289
performer 289 intake

 

i thought it was stock intake? damn
haha

 

Heater elbow threads into the coolant passage just behind the t-stat housing. If you don't have a factory piece (brass with a tube dropping down into the coolant stream), or if yours is corroded beyond repair, pick a new one up from Glazier's or NPD. The proper part will help prevent sucking air through the heater core, and is necked down at the elbow to keep from blowing out the heater core during high-rpm operation.

The temp sender threads into the front coolant passage on the d-side, opposite from the heater elbow. You may need a bushing for the sender; I can't recall if the threads on the Performer 289 are bigger than stock or not.

The other threaded piece is a vacuum block. It goes in one of the rear intake runners and feeds vacuum to the a/t (if you have one) or any other vacuum accessories you may have.

Use liquid PTFE (teflon) thread sealant or a dab of Permatex #2 on the heater elbow and temp sender threads. Use teflon tape on the vacuum block.

 

ok thanks starfury
that should cover it...

except.... my stock intake didn't have a vacuum block?
i looked at the picture online, and it looks like this is what i had instead...

Err...no pic=/
