Dave that is the same dilemma I went through. I just bought a real nice aftermarket Pulley took it to a machine shop and had it drilled to fit....Total cost was about 50 bucks! a bit steep, but I know it fits, and is balanced... and it looks very clean. I did the same with the Alt., and Water pump Pulleys also, that matched the lower crank Pulley. It gave me nice strong lightweight pulleys which look like some of those pricey Pulley sets, that are way over priced. All in all I spent $125 for all new pulleys. and it dressed up the engine nicely. It also lowered the rotating mass which we all know frees up power. My whole dilemma started after the water pump pulley developed a few hairline cracks, which I found worrysome...

maybe this picture will help clear up some confusion. I have my needs sorted out but for others with similar questions.
my original 352 had a single sheave marked c8ae-6312-b and I'm upgrading to power steering (and maybe some day A/C) so I will be using a triple sheave marked C8AE-6312-D. I Added the double sheave so people could see for certain that they're all the same diameter and fitment for the water pump belt.
if someone will let me know if i've screwed up the part numbers I'll modify and keep the accurate image posted for future needs.

There is a great place in Redding, CA that can probably help you with any harmonic balancer problems. They rebuild dampers on all models and if you have a special need, they can probably take care of it.

rancherogirl, welcome to the family of Ford Truck Enthusiast, welcome to FTE!! Thanks much for the referral, topic comes up frequently. 
After several weekend salvage runs seeking a dampner for 65 390 and ending up with several pulleys and dampners that I had no use for it became clear to me I should try and remember to 'bookmark' Bill's, affectionately referred to as NUMBERSDUMMY, post/threads for future references. Here's a couple on topic- Just a reminder, these links are few years old so don't get upset if source nolonger exist!!.

C3AZ-6312-E .. 1960/67 FE harmonic balancer has been reproduced, available from Dearborn Classics in Bend OR, probably other repro parts sellers as well.
Edit: Carpenter has it ($120.00, same price as Dearborn), but it's listed under the WRONG
part number (C3AZ-6312-A). Only the applications are correct.

I have a similar situation. I am trying to install an aftermarket AC system to a 66 F100 with 352 engine. According to what I read on this thread, I may not have a 66 model 352. The crank pulley has 3 sheaves with a 4 bolt pattern. The power steering pump and mounting hardware looks different than other pictures I've seen of a 66 F100 352. I need to identify which engine and year model I have in order to get the correct brackets to mount the compressor. I also need to determine the proper belt configuration. I'm hoping somebody on this form can help with this.
Thanks, Russ

Russ there are casting numbers for the block on the underside of your block... that will at least give you the block casting date.. On the right hand side of your block (passenger side) at the front edge about 3 inches above the oil pan mating surface will be a code such as C6ME-A or similar that will give you a starting point then post it on here and we can decode it for you.... Also Check on Ebay there are usually a few sellers with something that might work for you....

C6ME-A or similar block casting numbers are foundry marks, cannot be cross referenced to Ford part numbers. Are worthless for ID'ing the engine size, what vehicles it was installed in.
Some casting numbers were used for more than one year, and all FE engines were originally cast as 352's.
Harmonic balancers include a single sheave pulley, FoMoCo offered accessory outer: one, two or three sheave pulleys that bolt to the balancer.
These outer pulleys and the balancer will have ID engineering numbers stamped on them.

Thanks Bill. Where would I find the casting date code on the block? I could not find any numbers on the pulley. I looked inside the bell. Would it be stamped somewhere else? What year models of the FE engine had 4 bolt crank pulleys?

If there's no number stamped on the harmonic balancer, it's an autoparts store replacement.
The number is on the side of the balancer, not on its associated pulley
How many valve cover bolts per side does the engine have?

Each valve cover has six bolts. I could not see a number on the balancer but I was looking on the outside radius and couldn't see all the way around. Do you have to take the pulley off to see the number or actually remove the harmonic balancer to see the number?

Harmonic balancers have a single sheave pulley made as part of it. If the pulley comes off, the balancer is no good.
Take the outer pulleys off, see if there's a number on them, because the engine is either a 289/302 or a 351W.
Post the 4th digit of the VIN, when decoded the original engine size will be known.

My 66 HB has the single sheeve 3 bolt pully. My 76 parts F100 has a 3 bolt 2 sheeve pully, it bolted right over my 66 HB.
I have no idea if the 76 parts truck has the orginial engine or not. I was told it is a 390.

Well, the vin# is F10AN872037
I cleaned the block as best I could and did not see any numbers above the starter. I was trying to avoid taking off the crank pulley but I guess that's the next step. Wish I could post a couple of pictures.
