long vice short water pump
Folks,
I have posted on this before, but now need some more info. I was planning going with my long water pump, but had to move my motor .5 inches forward, now it really looks like the long water pump and set up is really close - using the stock radiator and position...anybody done this (using the long water pump with the stock radiator)...? If I have to get to the short pump, I will have to figure a new way for my alternator bracket - I wanted to run the alt and the power steering pump in low positions (alt on passenger side, p/s pump on driver's side)....I am interested in suggestions.... |

Re: long vice short water pump
They probably will need to know what fan setup you are running and a photo or two always helps.

Re: long vice short water pump
I used a radiator from an LCF GMC in my truck which placed the end of the water pump shaft about 3/8" from the radiator even though it's a short shaft pump. A mechanical fan is out of the question. I used a stock 12" GM electric fan on the front of the radiator. I haven't had any troubles with it since I built it in '93.

Re: long vice short water pump
long water pump, big truck radiator in stock 6 cylinder location, mid 70's fan shroud, after market aluminum fan. Fan required 1" shim to center in shroud. leaves about 3-4" clear to radiator. If your radiator is in the stock v-8 location a short water pump will work, that is what they came with. Long water pump crowds the radiator.

Re: long vice short water pump
LCF is Low Cab Forward, 2 ton? and up.
My truck's an original V8 so the radiator is maybe 5" closer to a V8 engine than the 6 cyl truck mounting location. The radiator mounting brackets were modified so the radiator would fit in the stock 1/2T Chevy location. Hmm... looks like the radiator isn't as close as I remember. Guess that means I'm officially getting old. But I do know the angle of the fan and the angle of the radiator weren't the same and there wasn't enough room for the fan at the bottom. Maybe that's where the 3/8" comes from. |

Re: long vice short water pump
Here's some pictures - I measured this, it looks closer in the pictures - it is about 1/2 inch. I could make it work...I would have to put an electric fan on the front......the x-like metal rods seem to be in the way (not in the pics).

Re: long vice short water pump
I saw yours and you are using a later model radiator - I have the stock one. Would a later modek be narrower, but still cool effectively? Also, what fans are those you have?

Re: long vice short water pump
Does that pulley have countersunk bolts? I can't see any bolt heads.
A Ford Taurus fan is a great choice for a lot of vehicles but I don't know if it will fit with stock X braces. BMW uses some small fans that aren't too deep and move a lot of air. I've used those for projects. |

Re: long vice short water pump
your motor must be way forward from the stock location.
check out your radiator mount, it looks like tour radiator is moved back and tilted compared to mine. a radiator shop might be able to move it forward on the mount. my truck was an original v8 truck, maybe the I6 radiator was back a little

Re: long vice short water pump
i just pulled the ramjet specs out to make sure that i wasn't misleading you, yes it is a long water pump.
i'm running a fatman mustII x-member on mine. here's the best picture i could find of the firewall clearances the bump out in back is for 2 big plugs that come out of the back of my distributor. your motor mounts look about the same as mine on the centerline of the x-member check out the radiator location in this pic and compare it to yours i know the 58-9 rad support is different, not sure how much.
