For clearance issues i need to find around 1/8" space between the snout of my water pump & rad. mounted electric fan, so rather than pull it all apart & take a strip off the shroud, does anyone see a problem with grinding a tiny bit off the snout of the water pump shaft?
Balancing issues came to mind but, its such a tiny amount to remove i think its ok,eh?
It doesn;t touch the fan now, but, its just sooo close, i need the peace of mind!

Shouldn't be a prob. I pulled mine apart and pressed the pully hub back for belt alignment. It's just a machine part and the closer to center, the less likely any balance difficulty. You are right to worry though about clearance since the engine does get around some under power on/off and bump/brake situations. Just take care to deal with excess heat. The aluminum pully mounting hub is a dandy heat sink to wrap a wet rag around for dissipating all those pesky BTU's.
Saw a nasty example of that at a cruise in last summer. Very pretty 29 Ford hotrod, overdone IMO, that went over a speed bump slow and still bounced the engine on the mounts which caused the crank pully to drive the vee belt onto the steering rack. Belt disintigrates and there is no way to replace it save dismantling the car because the belt wouldn't even fit between the pully and the rack to install it.
While the car was beautifully done, there was no thought applied to how to maintain or repair it or any kind of normal "what if" situations.

Well, you do bring up a good point, what if i throw a belt!
I don;t think a new belt would squeeze through the small gap between w.pump snout & head of electric fan, about 1/4" maybe!
this is before i;ve touched the snout/shaft with a grinder though.
Be a bit of a pain to change, 4 button head bolts holding fan/shroud on, but, nothing like that 29 would have to go thro!
Thanks

The 29 had a really trick electric fan on it. It was belt driven with the motor way offset for clearance. It was stupid tight in there. Not only was there no vertical clearance between the pully and the rack, there wasn't enough clearance between the fan housing and the water pump snout either. Apparently Ford Racing makes a super short pump that is available through Summitracing.com that might help you out.

I touched the pump snout shaft with a grinder & low & behold, i can just squeeze a belt between the head of the fan & the pump snout.
I really like the new, improved Flexalite Varible speed controller.
1- won't let the fan even kick in for 1st 10 seconds, to allow for start up.
2- Once you set it at temp. you want it to kick in, it starts off at a really slow speed & then ramps up depending on your water temp. So you don;t get that big kick to your electrical system on fan start up. I;ve read, at Ford Muscle that the power hungry Taurus fan, can spike at 50-70 amps on a hard start up!
I only connected the Hi-speed wire, if necessary, this thing will really move some air!
