What problems will I have with a V-Belt, long pump SB pulley setup in my 67?
 
I'm in the setup stages of the motor swap portion of my build up, & I have a running 327 with a long water pump V Belt pullet setup that I'm planning to put into my 67GMC. I'm wondering what problems will I run into with this setup? Lower rad hose? Shroud/clutch fan issues? I'm sure this has been seen before & I'd like to not have to collect a whole other set of pullies & brackets for a short pump setup. I'm going to place the motor in the correct V8 location. Thanks for your help & advice!

If you get all of your accessories for a long pump style engine you should be fine. Your alternator will be on the passenger side though so you might have to make the wires longer is all. Im not sure about the clutch fan, but Im guessing it will have to go.

I maybe wrong but...You swap from a long pump to a short pump you will need all new brackets.

As indicated, you'll need the acc brackets that match your water pump. if you don't have them already, I HIGHLY recomend getting them ALL from one car... or a couple cars of the same make/model/engine. There were quite a few variables over the years, and if you don't get it right, you'll be pulling your hair out.
An other advantage to getting them all from one car, you can get the belts for that year/make/model/engine when you dgo to the parts house, which is WAY easier than trying to get the right belts based on length and width of the pullys.

I have all the brackets on the motor & it's running true & straight. I was looking at the fact that these trucks didn’t come with long water pumps. I was wondering specifically if I would have a problem with getting the right lower rad hose or getting a fan shroud to work with my clutch fan. Thanks again!

You may run into a problem with the long pump sticking the fan and clutch to far inside the shroud. Since you say clutch I assume you are going to run A/C on this truck and if you do then you want about a 1/4 of the fan blade inside the shroud and the rest out.

I shortened my shroud by 1-1/4" off the lip. Seems to work well.

Honestly, if you have a good rad and pump, you can probably get away running without one.
My old small block longhorn, and small block c/1500 (same engine in both) never ran hot, and that was in texas... one was with the short pump, the other was long... then my caddy big block longhorn never overheats either... none had shrouds.
