SB water pump • The Dodge Challenger Message Board

I am in great need of a chrome or billit water pump for a 340. Edelbrock does sell one but it is $300.00. Does anyone know where I can find one before I spend that much? Thanks

Shatar, are you looking for a belt driven OEM style pump or electric billet?

I am looking for the belt driven water pump. I have looked everywhere.

I dont think I have ever seen a billet pump that was belt driven, when there are so many aluminum casting ones out there, and of course there would be no H.P. gain from using one. How about polishing the aluminum casting yourself? 300.00 would buy you a new casting and a dremel polishing kit! Unless of course you wanted a billet chrome electric, they make street versions now that last for 5000+hrs. BTW, nice 340 man, I used to run one in my 1973 Ply. RR back in the mid 70s

I was going to suggest the same thing. Polish it yourself.

He's talking about the "pump" Dave! :s004:

Steady Eddie.

You guy's are a crack up.

With all of the pockets and channels it would be a tough job. I think a dremel tool would be needed for most of the areas. Go with the chrome plating IMO.

Jon, I didn't think about this but could a person "tumble" polish one? You know the vat or container which contains walnut media or sand? Then it would polish it in a few hours?

It took me a couple of days to polish a Holley Street Dominator intake that I did back in the early 90s. It came out very good. It was hard work but very satisfying. :nod:

I guess a tumbler might work. At least it would get you most of the way. I think the seal would need to be removed though. Never done that before.

Polishing would be a good rainny day project. What do you think, 8 hours plus to do the job? What kind of clear coat did you use to preserve the finish on the carb Dave?

by **Eddie** » 15 Apr 2007 16:30

I don't know about Dave, but I have used successfully, Eastwoods Diamond Coat Clear for metal surfaces. Around 8.00 a can

I used to just give it a going over with chrome paste once a year or before a show.

I would love to have it chrome plated but I would have to disasemble it. I don't know of anyone that has even tore one apart to give me pointers on it. I guess I'll have to hand polish it.

Beautiful 340 engine there shatar. I too would want it chromed. Have you thought about an electric billet chromed one?

by **shatar4** » 16 Apr 2007 0:02

I have thought about a electric pump but I'm not sure on the reliablity of them. I would hate to be on the road and it goes out. With a belt driven, every auto part store has one of those.

by **Eddie** » 16 Apr 2007 15:16

Some factory cars and trucks now come equipped with an electric water pump, so why shouldn't a CNC billet Mezeire or Moroso one last as long. They "claim" 5000 hrs. before inspection. But I think your'e best bet for reliablility,looks is a polished one that you did yourself. Whatever your choice good luck. How much power does that 340 put out? My favorite was the 2.02 heads and the 1968 cam,(solid) and Thermoquad. I beat a lot of ford and gm cars with it on the street.
