Long vs short water pump
R. - I may be swapping my weak 6cyl in my 66 chevelle for a later model 454 and I'm wondering which power steering brackets to use and work with the existing car. Will the brackets for a 70's truck motor work? Thanks Rob
B.T. - Depends if you are going to use a short or long water pump. The 66 had the short water pump and if you use the long water pump your fan will be very close to the radiator and the fan shroud will not fit. If using the propper short water pump you will need 67 or earlier brackets to mount the steering pump the later truck brackets will not work.
D.C. - When we installed the 396 in my son's 67 SS I used the power stearing pump, brackets and reservoir from a 71 Suburban with a 402, using a short water pump and mounted the alternator on the driver's side. It almost looks original.
G.M. - For the short water pump setup, 68 brackets will also work, and big block p/s brackets for 66-68 are available through the reprodution places. One thing though, on 68 and ealier the power steering pump on a big block had a externally mounted reseviour, so your existing pump will not work with this setup. I don't know if the existing pump would work in a long water pump setup or not.
R. - Does the long water pump for the later big blocks work in a 64 to 67 chevelle or do you need to use the short water pump and accessory brackets. When swapping in a big block what is a good setup for water pump, pulleys, brackets, and is their a good place to buy the whole setup. Like year one?
B.T. - You will need the short water pump and brackets for a 64 to 67 chevelle. If you use the long water pump the fan will be too close to the radiator and the fan shroud will not fit. I do not know of a one stop shop for your brackets.
L.I. - I went through Muscle Factory to get all the brackets for my 67 big block. As for pulleys, since I wasn't going the stock route, I went with March underdrive pulleys through Jegs or Summit. The aluminum looks great and maybe adds a few hp in the process.
K.T. - Ted Williams Enterprises, 5615 Route 45, Lisbon, Ohio 44432 probably has the parts you need. Phone (330) 424-9413. He has quite a selection of brackets and pulleys. Check out the deep groove pulleys that are available.
A.J. - How stupid I feel. 1000 times for 25 years I have heard of long and short water pumps. How long is long and how short is short -- Measured from where?????
T.J. - Small block chevys used short leg h2o pumps on all passenger cars thru 1968 and on all Corvettes. The mounting surface of the leg(block side) to front of pump housing(non outlet side) is roughly 2 inches. Big block chevys (yeah) used short leg pumps from 1965 thru 1968 and on all corvettes. Pumps after this time were long leg design. Mounting surface of the leg to front of pump housing(non outlet side) is roughly 4 inches. Note: Though the name is the same, the small and big block pumps are not the same. Big block pumps have a bypass provision on the top of the pump, little blocks do not.
