Tri-Power Intakes - Identification
Post your pictures of various year Pontiac factory Tri-Power intakes, to help aid in identifying them for those who are looking to put together a Tri-Power setup. Also post pictures of the correct thermostat housing for each intake if you can.
Hopefully we can end up covering all of them from 1957 through 1966. 1959, casting # 532422 The bare intake weighs 39.45 pounds.     Correct cast iron thermostat housing for 1959, with built-in engine lifting loop. As you might imagine it's quite heavy, weighing in at 2.85 pounds.    Here you can see how the lifting loop configuration of the thermostat housing was copied in .150" to .175" thick stamped steel for later engines, attaching to one of the studs that mount the timing cover.

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.
