Edelbrock Victor Water Pump

As part of my engine makeover I was planning on replacing my existing aluminum water pump, for which I have no part number or details, with a high flow Edelbrock Victor water pump #8841. Dimensionally the Edelbrock pump is 5.42 inches from the flange to the end of the pulley. My existing pump is 5.125 inches. This is going to move the fan closer to the radiator but unless I do something my pulleys will not align, what are my options.

Also the Edelbrock pump has a back plate, what does this mean?
 
I was going with new pulleys when I installed my Victor Jr water pump, not that this should make a difference. My Harmonic balancer (summit S.F.I.) came with two lengths of spacers. They looked like thick washers. I used both to get the pulleys ligned up and altogether it pushed the pulley out about 1/2 inch. The backing plate is the flat plate that bolts to the back of any waterpump. The Victor Jr has a very different backing plate than other sbf water pumps. When I went to the new balancer I had to grind some of the bottom of the water pump for clearance. It did rub a little.
 
I'll check out what other pumps are available.

However, if I'm only talking about an increase in distance of less than .3 inches, as in the case of the Edelbrock pump, is it acceptable to use spacers (washers) to move out the power steering pump, alternator and balancer so the pulleys line up with the water pump or is this not good practice?
 
Early Timing Chain Cover Experts

I'm learning all the time here...............

OK. I think I've found out that there are two types of timing chain covers for small block Ford V8's. The early ones have 9 water pump attachment points (holes), the more recent ones have only seven. The lowest two holes are omitted on the recent ones. My timing chain cover is original, circa 1963, as best as I can figure from the casting number. It has nine holes, so the #8841 Edelbrock Victor Pump will not fit (properly), having only seven holes.

I have a high compression 302 small block. So my questions are:

1. Am I correct about the differences between the timing chain covers?

2. I need a passenger side oil inlet water pump, I don't think the #8841 is the right pump I need. I think that the #8842 might be better. The distance from pulley to the back of the pump at 5.16, on the #8841, is closer to the 5.125 (measured) of my existing pump. Has anybody been in the same postion as me and do they agree.

3. As the Edlebrock #8842 pump is for the 'K' code 289 does anybody know how it's flow rate compares to the #8841 pump.

4. What is the Felpro (or similar) gasket number for the nine bolt original timing chain cover.

Thanks in advance.
 
I have an Edelbrock water pump and I found that I had to grind a little off the bottom (I mean like 1/16th of an inch) to keep it from rubbing on my balancer(which is also aftermarket).No matter how good of a brand you buy, there is always a chance of mismatch on supposedly bolt-on parts. On the plus side March makes pulleys for exactly my combination, so everything lines up groovy( bad pun intended).
 
I did have to grind my timing chain cover also. I ran into the same problem with my 5.0 aluminum water pump I installed on my early cover. You can still use you victor if you want. Take of the backing plate. Take both down to someone with a press. Have them press the piece the holds the pulls down the hieght of the pump you have now. I had to open up my hole on the March pulley when I did this to get it to fit, but I really don't care. I needed taht pump because of the radiator I got, didn't want a cast pump, and it has lifetime warranty. Plus I didn't want to pay the coin for an aftermarket.

I too had to grind the water pump housing a little to clear the balancer on a new, but different brand, aftermarket water pump.

I had issues trying to install the new one and discovered the lack of clearance to the balancer kept me from bolting it on. I compared the new pump to the original Ford pump and you could see that Ford had the same boss but had pre-clearanced it. I simply copied the shape to the new pump.
