65 V8 long water pump, FAN SHROUD ideas? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

NEWFISHER · 01-25-2014, 03:55 PM

A stock one won't fit and I don't want to cut up the perfect oe one that I purchased to make it fit. An aftermarket plastic one won't work and if cut down will have too large of fan opening by the time it fits ( 4" from rad to center blade)

Anyone run into this? Solution?

My thoughts are fab up a nice sheet metal shroud or ditch all of the LWP stuff from the front of the engine and go with Short Water Pump stuff.

Hoping someone says " oh yeah, just get a shroud from a ______and trim it

That's why I typically stick with short water pumps on the vehicles that originally came with them. Is your engine in the original location? I have seen other members run the long pump with a stock fan shroud, but when I tried it once, it didn't work. Not sure what the difference was.

I`m running the short pump, engine mounts in the rear hole of crossmember, with fan shroud and 2.5 inch fan spacer, so theoretically I can change to a long water pump if I decided to change everything else, biggest issue is what holes the owners are using in the mount/crossmember..

^^^^^^ NICE! Now how good are you at shoving small cameras into tight spaces and getting a few pics? I would love to see which fan and clutch they are. My fan is flat and bolts to the backside of a fairly small clutch. Does the end of the taper area of the shroud land about half way through the fan blade if you dropped a plumb bob?

Thanks James!

I doubt you want to go electric fan but if you do I used a Lincoln Mark VIII fan. I had to trim a little off the top of the shroud to clear the radiator tanks and the radiator hoses and fab up brackets t mount it but I think it looks like it belongs there. While I was at it I installed a Radiator Overflow/Windshield Washer combo off a Ford Exploder.

That's a nice looking engine compartment! Thanks for the idea , but trying to stick with the parts I have ( cheap ). I like the washer/res you came up with too. Hopefully you ground off the blue oval! hehehe

Thanks James, that fan clutch looks identical to what I have and that fan looks aftermarket??

duallyjams · 01-28-2014, 10:48 PM

The fan is off of a GM truck, I got it from board member teeitup he deals in 67-72.

Rich 5150 69 · 01-28-2014, 11:32 PM

Newfisher, do you realy need the thermostatic fan, if you just bolted on a 5 blade stock fan it would put it right where uou need it..?

61K10 · 01-28-2014, 01:37 PM

ck out a chevelle big block 66/67 shroud. they are a little wider and bolt on flat but real short. can take a pic and measure if you want.

That would be great. Measurements too if it's not too much to ask.

Thanks!

NEWFISHER · 01-29-2014, 01:23 AM

I have found that a 86 suburban 350 fan and an aftermarket fan clutch with NO shroud runs cooler indicated on the gauge than an aftermarket fan bolted direct drive to the pump without a shroud.

61K10 · 01-29-2014, 02:04 PM

here is some pic's of the BB shroud--could be modded to work i think
27 1/2 wide
16 3/4 high
2 1/2 thick
19 1/4 fan opening

NEWFISHER · 01-29-2014, 02:08 PM

Thanks, I will measure mine tonight!
