........T...................--- Oil Pump & Water Pump ---
.............................................
I ran into a real headache with the oil pump pickup. I could not find an off the shelf pickup that would work with my Melling 10550 pump and with the deeper 7 quart Moroso pan. I wanted to use both of these, so the only solution I came up with was to get a Moroso #24861 U-Weld-It Extended Oil Pump Pickup and make my own pickup for this application.
............
I bolted the bracket on and then using two squares determined where I needed to cut it off so that I could weld the screened pickup box to it at the right height. I knew the depth of the pan and the height of the pickup box so with a little adding and subtracting I came up with where to cut the bracket.
............
After I cut the bracket (left arrow) I tacked the pickup box (right arrow) to it. Then I took the pickup tube and figured where to cut it so that it would both mount in the box and in the pump body. This wasn't as easy as it appears, but I finally figured it out.
............
Then I tacked the tube together and the tube to the box.
............
When I was happy with every thing I brazed the tube to the pump and welded the two parts of the tube together and the tube to the box with the tig welder.
............
Then using a one piece pan gasket I put the pan on the block. One item that I had to come up with was the housing that holds the one piece rear seal on to the back of the block and that the pan sits on. If you get a bare block try and get that piece at the same time.
............
You can see I now have the bottom front pulley on for the water pump and power steering and the motor mounts on. I gave serious thought to using a newer LS series motor, but in the end it was just to expensive to do. If I would have been looking to build a motor for the 500-600 hp range I would have gone that way and it would have been about the same cost or maybe lower, but I wanted to get into the 600-700 hp range and to do that reliability with the LS would have required a 4340 rotating assembly and these still aren't cheap. Also my truck was already setup for the old style motor pulley wise and mounts and headers, so this combination won out.
............
Next up came mounting the water pump. I had two problems here. One was a clearance problem between the pump and the timing cover on the passenger side where the pump bolts to the block. A little grinding there took care of that.
The second problem was the pump pulley and the crank pulley didn't quite line up. If it was my old 5000 rpm motor I probably would have left it alone, but since I want to run this motor over 6000 rpm I figured I'd better take care of it.
............
The top pulley had to move out about .090 of an inch. I had some .090 aluminum and clamped the fan spacer hub to it and drilled 4 holes.
............
Next I located the center hole and drilled it out. Then................

............
Here it is mounted (right arrow) and the left arrow points to the the area where I had clearance problems between the pump and the timing cover.
............
Now the alignment looks good to go.
