Really nice

January 13, 2016
This is really nice setup for putting a sbc in a model A ford chassis. The quality is very nice. I removed the bracket for the AC since I am not running AC. Bleeding the air out of the system is a real pain..I wound up using an air lift system. The 6 cly pump in my opinion is not up to snuff on engines with a lot of horsepower. I never had overheating problems until I installed an engine making 400hp. I like the riser and a mechanical fan, so my next step is to try a high volume 6 cyl pump. I still would recommend the riser, works best with lower hp engines.
Yes, I recommend this product.

Zip riser runs a mechanical fan on small block Chevy

December 20, 2015
I bought three items: the Zip riser, Chevy 6 cylinder water pump and a shim kit. I had a Zip on a previous '32 roadster and it allowed me to raise the fan line about 5 inches, centering it in the radiator. I then used a flex fan and a shroud I made to make my 383 run cool in all weather. I like the idea of using a mechanical rather than an electric fan on an old school hot rod. I'm building a new '32 roadster and will use the Zip riser on it. I also like that the casting quality is good enough to clear coat to feature it, or paint it to subdue it. I like the built in alternator mount too. I'm not using AC so the AC mount won't be used. It's a good idea to drill a small bypass hole in the thermostat to let captured air escape. The Zip has a small screw at the top to bleed off captured air (a must). The screw is easy to drop and lose. A brass air bleed off valve is available from GM pt# 10070107. You will have to drill out the hole and tap it to 1/8"pipe thread.
Pros:
  • Nice Casting Quality
  • Gets Rid Of Electric Fan
  • Good Enough To Clear Coat
Cons:
  • Ac Hardware Is Crude
Yes, I recommend this product.

Good problem solver

February 18, 2015
I bought this riser kit because I'm putting a small block chev in a 28 Model A, and the fan position is so low it almost hit the lower hose. I don't like electric fans on traditional rods, so the answer was to use the Zips riser to get it up about 5 inches. Worked perfect! I Don't expect any problems, although I haven't run it yet. Brackets are a little hokey, but they work. Good problem solver.
Pros:
  • moves fan up
Cons:
  • hokey brackets
Yes, I recommend this product.

Where's the directions?

March 28, 2012
The water pump riser serves its purpose perfectly and looks great. The accessories that came with the water pump riser are subpar. The brackets were pitted and tarnished, the spacers were very light weight and where are legible directions?
Pros:
  • Riser fits perfect
Yes, I recommend this product.

What is the finish on the riser? Does it come in a polished or chrome plated option? I am using a crate small block chevy in my truck. The center of the pump shaft now lies in the lower 1/3 of the radiator and this kit will solve my cooling problems. I know I can get a Tuff Stuff chrome plated water pump for this installation but the alternator and air-conditioning compressor are all polished or plated and I would like to stick with this theme.

Mine came rough cast aluminum. I'm sure you could polish it if you want to put the time in.

This riser is cast aluminum. Sorry we do not offer it in a polished or chrome plated version. It could certainly be polished if a person wanted that look.

From the block surface out with the Zips riser and suggested pump the fan hub face is 5 5/8” from the block which is suggested dimension for the short small block water pump.

The replacement bleeder valve is AC Delco part number 10070107 or Dorman 902112. Sorry we do not offer that item but a local auto parts store should be able to get one for you.

I want to put this riser on my build but need to know if it will work with a power steering pump. Not sure what pump i will end up using it needs to be located above the lower pulleys, was think of the type 2 pump mounted on the head.

The water pump riser will put the alternator and A/C compressor above the water pump ports with similar configuration of 91667919 as the photo on our website illustrates. Use of head mount bracket 91032904 and pump 91032906 will likely work as long as your application does not have interference with the normal pump location when head mounted.
