aftermarket water pump problems?

I bought a rebuilt '85 302. Originally serpentine belt system and fuel injected. The builder converted it to carb. I am going away from the serpentine set up in part because the serpentine system is missing. I bought an old school V belt system from CVF Racing that required the lower outlet from the water pump to the radiator to be on the driver side. I bought that pump from STEWART COMPONENTS. During mock up I noticed that the STEWART COMPONENTS water pump has 7 bolt locations while the original pump had nine. The gasket they supplied has nine holes...curious. The missing bolt holes are near the inlet and outlet of the pump. I saved the bolts from the old pump. They only protrude from the pump about 1/2" and don't appear to go into any water jackets. Looks like they are there just to assure a good seal around the inlet and outlet. STEWART COMPONENTS could offer no assistance saying that Ford did a lot of weird things. Any thoughts? My timing chain cover is marked RF-E7PE-6059-AA. My new water pump is clockwise rotation. Thanks

bummer your not keeping the serp setup as its far superior. anyhow you will need to change the timing cover for this to work correctly. finding one from a carbed/Vbelt motor would be the ticket.

you could probably find and keep the serp system by pulling off a wrecking yard motor and would be far easier down the road when a replacement part is needed.

I am a novice so please don't think I am questioning your advise. I am not. I have a friend well versed in Ford motors who will undoubtedly disagree. Going to serpentine is out 'cause I'm $500 into the pulley system. I have seen this topic before and never really understood it then! I think it revolves around the water pump rotation and the orientation of the water inlet and outlets. I will have to give him some factors to consider or he won't take it seriously. Can you tell me the factors so I can covey them to my friend? Even when he is wrong he is still much smarter than me. I don't want to do this twice!!!!!!Thanks for your time, Matt

Well with an E7 timing cover, that's not an 85 motor. I suspect the E7 cover could be the one used with the pickup/van 5.0 and 5.8 which are reverse rotation with the revised coolant ports that don't mate up to a std rotation cover. Now as for the inlet/outlet part, only the early 289/302's had a different inlet location (passenger side), the "outlet" ports (there are two "outlet ports) are on the backside, and these were revised in 87 to smooth out the flow into the block.

Here is a picture of the different timing covers.

You can see the 7 bolt vs 9 bolt difference.
