Just replaced the *original* water pump on my 606 engine with 335,000 miles on it. It was not *needing* replacement, but since I already have the head off, and everything is accessible – I figured why not…It’s served its purpose long enough to warrant a replacement. (Plus I don’t want to take any chances of frying my freshly-headed motor).

My 617 has 234,000+ miles on it, and I did replace that water pump around 200,000 miles or so, but it was probably already on pump #2.

The V-8 gas guzzlers (116 & 117 series, including the aluminum 117’s) seem to last about 70,000 – 80,000 or so.
