So you want to run a Tri-power on your Pontiac engine but you don’t have the “Tri-power Bulge” in your timing cover…. No worries!  We got you covered!!

This is our aluminum Pontiac Tri power water neck which is modeled after the Stock 1966 unit.  You can use this water neck / thermostat housing to run both stock and aftermarket Tri-powers with both early (1968 and earlier) or later (1969 and later) stock and aftermarket timing covers that do not have the Tri-power provision (recess in the timing cover).  The hose end points to the driver side of the vehicle and will accommodate a stock size 1.5″ radiator hose.   This is an aluminum piece that we designed from scratch using MasterCam and it is machined on one of our in-house Milltronics CNC milling centers.  Water neck does not come painted.

Quality Pontiac Tri Power parts MADE IN THE USA!
