Wow Daja Vue I just posted this in the Blazer side, My new ride has a Flex_Lite fan and no shroud Scares the crap out of me. Thinking of running Electric myself.

I don't have any pics but I installed one on my truck, but it is only a small block. I tried to use it with the factor schroud but couldn't do it and didn't like the way it looked by itself. I did trim mine about 3/4" so it was less than 5 inches talk at the motor

ttt gotta be some guys on this forum running mark VIII fan with a big block

[ofnaman]

I have a bbc in my truck with a short water pump with a 14" electric fan. I left the fan shroud in for hwy driving, but I am going to take it off. The truck never gets hot, as it has the huge 4 core radiator in it. There is about a 1/4" gap between the water pump shaft and the fan motor. I could have offset the fan, but I like it centered. Sorry, no good pics yet.

Saw this write up and this is the way I'm going. http://67-72chevytrucks.com/vboard/s...=electric+fans

Already got the fan and relay kit ready for the install.....

I tested this inside the shroud and it moves some serious air.

Do a search on Mark 8, When I was looking I remember there was a memeber that had installed it and he was running a 396 with no problems. I think he had to trim it but that is not a bid deal. I just sold mine last week, it was ready to mount.

I have one installed on a 68 core support w/a 4-row factory radiator that I can get a pic of later tonight after work.

It's not installed on a running/completed truck though. Currently it's just a mock-up (fan/shroud, radiator, core-support bolted together)..... Would that work for you?

[496stroker1]

sure SCOTI, are you running a big block? if you are how much clearance do you think you will have?

[SCOTI]

Not on this one. But, this one is a test for my other 'RestoRod' that will have a 'big' big-block. This one is sbc that has been moved slightly from the factory position (Dropmember).

I was told that those Taurus ones pull a lot of amps. Something like 45 amps. Just a thought in case you don't have the right alt or relays.....

[496stroker1]

yep i know. going with 100 amp minimum maybe 140. place in calgary has chrome powermasters for 100 bucks for the 100 amp and 140 bucks for the 140 amp.

[496stroker1]

scoti you said you moved the engine back a little bit? wonder if theres enough room to move a big block an inch or two back. il probly have the cab off so it should be a big deal just wonder about firewall clearance

[496stroker1]

should also ask what is the clearance with a big block with long water pump from pump to rad?

[clay68c10]

I have the mk8 fan and a 454 with a 4 core radiator. I had to trim the shroud and mounted it off center so the wp pulley would clear. I'm running a 105A alt and a PWM fan controller. I don't have any pics, maybe I'll come up with some this weekend.
With the BBC in the stock frame location, you'll have about 1/2" between the long wp pulley and your radiator. It was too close for my liking, so I stuck with the short wp setup.
This setup kept me cool all this summer without a/c. I got that working right about when it started cooling off (typical for me). With outside temps in the upper 80's it ran warm with the a/c on but never got too hot.

[496stroker1]

im still mulling the idea of a short pump, then i gotta find ALL the brackets for it and pulleys so i wanna stick with the long. definetly have to offset the mounting of the fan cuz it will hit the motor probly for sure. it will be close but i have i pic and if it hit around the area where i outlined i could probly just take out one of the fan supports and have the pulley go inside the shroud a bit as long as it didnt hit the fan. i dunno im just throwin some ideas around

You definitely won't be able to move a BBC back in these trucks. At the factory location, it's already pretty close to the firewall.

My sbc combo (in my Beater 68) will actually be moved forward (toward the grille) & up (crank C/L higher than stock) to clear the aftermarket crossmember & corresponding R&P that I'll be installing. I'm using a similar crossmember in my RetroRod 67 w/the BBC, so it will pretty much do the same thing.

As for pics . . .... I grabbed the camera but the memory card was full. I started scrolling through pics to delete some & actually found some pics I had taken of the set-up. But, when I tried to down-load them, the camera wouldn't do squat & I'm not sure WTF is going on. I'll try again this weekend if Clay doesnt beat me to it.

[SCOTI]

Ok..... I did some digging & found some pics of the 'mock-up' that I already had in an old thread here on the site. The ones in my camera are different because I had the tape measure showing various depths & dimensions.

Here's what I can offer for now . . .....

You don't have to center the fan, if you mount it to the driver side edge you should have plenty of clearance.
