Have a friend looking for the double groove water pump pulley for a 401/425.

Earl, Best to be more specific as to model and year because Buick varied the pulley diameters. Obviously, the car in question has AC? Just trying to help...

Thanks Tom, I'll try and get more info. I guess the engine number would work too right.

The two letter Engine Code would identify it best.

OK will try and get that. I do know it's a dual quad 425

Just had to find one for my Gran Sport ,but it was for the Crank pulley.

Don't know about that specific one,but mine has a number stamped on it.

I posted request on the V8Buick Site and found one relatively fast,for what I was told is a rare piece.Might be worth a try also.

in Addition, Carmen Faso in Tonawanda New York is usually a "Go To " guy for nailhead parts.He unfortunately did not have the pulley I needed,and does not "do" the internet ,so here is his contact info.Good Luck.

don't know if its the right part-sharknose on ebay is selling a dual pully-TN

some engine numbers, H 937815 & B-3644705

going by the 705 ending number it appears it is a 401, not a 525 as he originally thought. He said the H 937815 is stamped on the engine by the valley cover. Shouldn't there be two letters there also.

Rich and tnugent, I've passed on your info to him, thanks. But I think he needs to figure out exactly what he has before he goes looking.

,Don't know if it will help because he probably doesn't know ,but the part # stamped on the one I just needed and just received is 1368359. Hope that helps.
