If the above is accurate, it's the pulley that I need.
I think the long snout wp may have been a mid-year '69 deal and so the ones on the page listed by OG68, I think are still for the short pump. |
Never was a mid '69 model factory installed deal. The tall 11 bolt waterpump, the "124" was first introduced with the production rollout of the '70 models in mid August of '69. The oddity that took place is '69 Firebirds continued to be built up into Nov '69 & their engines from what I've noted over the years were built with the 351" casting (short) 11 bolt wp.
As a service parts procedure, Pontiac advised dealerships in replacement of original '69 waterpumps to install the tall '70 (or later) casting wp along with swapping to the '70 design wp pulley. This is easily noted in Master Parts Books. This service procedure worked fine on '69 A, B, & GP series cars, but not on '69 F-body's with 4core radiators.
