Long & Short Water Pumps - The 1947 - Present Chevrolet & GMC Truck Message Board Network

dooce · 06-05-2008, 11:41 AM

im looking to buy a serpentine belt kit for my truck soon. The one I like says specifically for long water pumps, and I dont see a short pump version at all similiar. Is it alright to change my short pump to a long pump and change everything else to match? Its a '68 327 if that matters. Thanks DOOCE

You can use a LWP on a 327. That's what I have on mine.

**Captkaos** · 06-05-2008, 12:47 PM

Are you sure it is a Short pump. IE can't get you hand behind it..
If you are getting a serpentine for a Long pump, everything else will match when you swap pumps.
There is nothing specific to the motor that will require a short pump except for the accessory brackets so if they are changing you are fine.

You may need a reverse rotation water pump.

dooce · 06-05-2008, 02:11 PM

how would i know if i need a reverse or not?

**Captkaos** · 06-05-2008, 02:30 PM

You don't have one if you are using normal V-belt pulleys.
If you aren't running a serpentine setup, you don't have a reverse flow waterpump.

dooce · 06-05-2008, 03:26 PM

the kit i am looking at buying is a serpentine belt kit with pulleys and all. so will i need a reverse w/p or not? you kinda lost me ^. its been a while since ive be able to mess around with the truck, but i think i am able to stick my fingers between the block and w/p. you can see the timing chain cover in the pic. thanks again for the help, DOOCE

**Captkaos** · 06-05-2008, 04:28 PM

That is a long pump. It is also standard rotation.
You are going to have to get a new reverse pump either way if you want a serpentine setup.

dooce · 06-05-2008, 10:58 PM

thanks for the help!

dieselarmy13 · 06-05-2008, 11:33 PM

Hey dooce, how's K-town nowdays? Sure do miss that place!

dooce · 06-06-2008, 01:18 PM

not too bad. its still the hang out for all the americans. Chucks, Thirsty Nellys, Hannen Fass, Nacht Shicht is the place to go. The euro rate is crazy right now. it flucuates anywhere from .62 - .64. How long ago were you here?

dieselarmy13 · 06-06-2008, 05:11 PM

I just left there last December. Man I miss ol' Chucks Diner. Didn't go many other places in that town, just did alot of traveling. But Chucks was the place.

Pushrod226 · 06-08-2008, 03:01 AM

All bs aside.... What kinda serpentine setup you goin with? You got picks??

dooce · 06-08-2008, 05:15 AM

im going to go with a zoops system.

dooce · 06-08-2008, 03:00 PM

is reverse rotation clockwise or counter clockwise?

Pushrod226 · 06-10-2008, 02:45 AM

http://www.zoops.com/home.asp

BTW standard is clockwise.

dooce · 06-10-2008, 01:58 PM

dooce · 06-15-2008, 06:10 AM

Pushrod226 · 06-15-2008, 09:45 PM

You don't need a reverse pump for either of those serpentine setups. Nice Kit wouldn't mind havin that myself.
