Need help with alternator

[RichardJ]

Looks like the original 10DN connector plug to me.

I have to agree with RustyPile that something is going on with the engine placement preventing the fan from lining up. Not that uncommon with K models as many that left the factory with I-6's and got converted to V8 's along the way. Judging from the your valve cover only I'm guessing the truck no long has the original engine.

If you want to correct the misalignment of the fan and shroud we will need more photos of the motor stands, the clearance between the firewall and the distributor, the transmission crossmember, the core support and radiator mounts.

I also understand you just wanting to get the truck running. Are you planning on using the truck as a daily driver? If so what summer time temperatures do you expect to be driving in? Would you expect to experience stop and go traffic? Knowing the answers to these questions will help us guide you to the right electric fan conversion for your needs.

There are hundreds of millions of vehicles with electric cooling fans on the road right now and they all were engineered to match the vehicle and its intended use. If you want the same success you need to do the engineering too. You also need to use quality components like the OE's do. They build and sell vehicles expecting them to see 115 degree weather and not overheat in stop and go traffic, for the life of the vehicle's warranty.

Avoid cheap parts as they were only designed to make you part with your money.

Your 10 volts at idle is common on many vehicles of this era. They were not engineered with stop and go traffic in mind. The rpm of the alternator at idle isn't enough to make the alternator charge by design.

No matter which path you chose to go doing the homework now will make for trouble free driving down the road. So trouble free you won't remember the work it took to get there.

Good luck and keep us posted.

here are some pictures and measurements. from the distributor to the fire wall there is about 3 inches max. from the water pump to the radiator there is 7 1/2 inches.

the radiator core support rubber is all new. the radiator support brackets and rubber is also all new.

I think the truck originally came with a v8. on the core support it has a sticker that says 350 v8. i am not sure if the core support is original to the truck or if the v8 in the truck is original or a replacement. the tranny however is a different story. the truck originally had a manual tranny. the PO converted it to an automatic. so i think this is where the misalignment is? here are pictures of the motor mounts and tranny mounts.i noticed that the front cross member is bolted in the middle bolt holes. im not too sure where they are supposed to be bolted at. i just ordered poly motor mounts and a small spacer to see if i can get a little more lift on the block. thanks for looking at my pictures and helping me figure out this mess.
