Brand new GM water pump and flexplate F/S - The 1947 - Present Chevrolet & GMC Truck Message Board Network

These are off my new GM HT383 crate engine but since I am going with a serpentine setup and a manual tranny, these are not needed. Came off right when I got the engine, so they have never been used. Should be about $10 for the ride for each part.

Water pump: is GM part # 88894341 $40 obo

Flexplate: GM Part #14088765 $50 obo

Outside diameter is 12 3/4" for years 1986-up. Crank Flange bolt pattern: 3.00"; Converter Bolt Pattern.: 10.75"; starter ring gear teeth: 153. For one-piece crank seal. Used with 5.7-liter HO engine. Torque converters for TH350 and TH400 transmissions are produced with both 10.75" and 11.50" diameter converter bolt patterns. To identify the correct pattern, measure from the converter center to an attaching bolt hole and then multiply this dimension by 2.
