I installed a Milodon Aluminum high-flow unit on my '66 289 this past weekend -- seems OK, although the impeller was stamped, not cast /forums/images/icons/frown.gif. On the up side, it had that anti-cavitation plate on the impeller, so...
$75.75 from Jegs, I believe, with both gaskets and back plate included. Installed no problem.
Now the ARP water pump bolt kit I bought, that's another story. The bolts are great (12 point SS), but the sizes weren't really optimum for my install, which I thought was pretty standard. In fact, I had to re-use the bolt that goes in just above the fuel pump, as there were just not enough bolts of that size in the kit to go in all the places that actually needed them. Strange.
It think it was around for at least 5-6 years. It didn't have a ton of milage on it, but I was a little concerned about the front bearing (it was still working fine when I took it off). It had a little bit more play than I liked. My 7000 rpm shifts back then probably didn't help much, lol
Slapped the high flow version on my 289 in the coupe and the operating temp went down about 8 degrees on average. The fit and finish were good, and it never developed a leak in the time I had it. I thought it was a good value against the cost of the Edelbrock. I paid about $80 from Summit Racing. Just my .0199999 cents worth. Cheers!
Yeah, I used one on my 289 for a bit over a year until the front seal gave out. I'm not a happy camper, since it has a whopping 90 day warranty as I recall. No racing or other abuse, just mostly highway miles. I went and bought a lifetime cast iron unit at Autozone instead of replacing the Milodon pump.
I just bought one and installed it (haven't run engine yet) but while installing it I noticed that it is exactly the same as the GMB pump (bought at Schucks/Kragen). They welded on a circular plate to the impeller but that's the only difference I can see. I'm not sure if they run a different bearing or not but the housing is the same, it even has the "G" cast into it. You can buy it from the parts store for 40 buck or so.
I've ordered a Ford Alum for $22 from NAPA. Better than $80 or $150. Plus with electric fans I should have no probs. Don't have any now with stock setup, just want to make it better./forums/images/icons/smile.gif
