Which water pump is correct?

I am trying to order the correct water pump, and after talking with a few suppliers I am getting progressively perplexed. With engine code 20D00008C, 3.5L Pulsair, non A/C, what is the correct water pump part number? These parts suppliers are seeing several possibilities. HELP!

According to the parts manual there are 2 types of pump for a stage 1 engine, that is assuming it still has its original engine in!

If you have a fixed metal bladed fan then its part number: RTC3661
If its a viscous fan (most common) then its: RTC3660

If you post a picture of the old one then, just incase its not the original engine, it will help identify it.

Do you have a copy of the parts manual?

Well, one thing is that my engine appears to be donated from a 83-85 model based on engine code. I have the plastic viscous-type fan. I have a parts manual, just wanted to ask you chaps, too. What do you think?

Does the fan screw onto the front of the pump or does it slide on and is held on with a nut and washer?

If its the latter then its RTC3660 if it screws on then its a rangerover pump you have.

If I remember correctly from when I took it apart, it slides on and is secured with nut and washer. . .

I ended up ordering STC1610 from Craddocks. It had my engine number on it, so I'll cross my fingers. . . .

you can fit any of the waterpumps up until the front drive change, I am not sure if they are still the same after they went to serpentine, you might need a pulley to match though. I am using a RR EFI viscous type waterpump on a P6 front cover for my new engine, I fitted a stage1 waterpump to my efi RR when I was picking up a load of stage1 engines and parts and the waterpump bearings collapsed.
