Let's move on to the top of crank pulleys. Y'all will remember that if I go with v-belts I want to run two of them to the alternator pulley to provide plenty of power to the 3G alternator. But, the stock pulley on Dad's truck has two different-sized middle and front sheaves so that won't work.
The other day Shaun was at the salvage and found a pulley from an 84 302 which has both those sheaves the same side. So, he bought it and shipped it to me. (Thanks, Shaun! ) I got the pulley in today and cleaned it up a bit, including running it through the blast cabinet. I've included some shots of it at the bottom of this post. But, I want to document things a bit in case someone else wants to do this. Here's what I found:
1984 302 Crank Pulley (D00E-6312-C)
Rear sheave: 6 5/8"
Middle sheave: 7 15/16"
Front sheave: 7 15/16"
1981 351M Crank Pulley (D0A?-6312-C3)
Rear sheave: 6 5/8"
Middle sheave: 7 15/16"
Front sheave: 8 7/16"
So the water pump, which uses the rear sheave, is going to run at the same speed with the 302 pulley as it does with the stock pulley. And the alternator will also run at the same speed as stock when running the 302's pulley as the middle sheaves are the same size. But the A/C is only going to run at 94% of the speed it would with the stock pulley, although I think I can live with that.
However, I'm confused about what I see in the catalog re pulleys vs what the pulleys actually say. (I bring this up since if someone is wanting to do this in the future s/he should use the number D00E-6312-C for the pulley and not those shown in the catalog.) Here's the page for the 302 pulley:
The first thing to note is that there is no pulley matching the # of the one from the 84. And, lest you think the 84's pulley has been swapped I should add that the pulley on Ray's 86 302 bears the same part #. Now, I grant you that the difference is only in the suffix, with the catalog showing a B and the pulley showing a C. Also note the catalog shows that the B pulley is a 2-sheave pulley while the C pulley is a 3-sheave. Could it be that A = 1 sheave; B = 2 sheaves; and C = 3 sheaves?
And, another thing to note is the phrase "refer to pulley I.D. chart, Section 60, Page 5", which is highlighted in red. I have two versions of the catalog that I think are from two different sources, and neither has a Page 5 of Section 60.
Ok, now for the 351M pulley. Here's the catalog page for it:
I've highlighted the # that Dad's pulley should be. But, as shown in the pic below, in reality it is D0A?-6312-C3. As you can see the 4th character is not legible. Oddly enough, the pulley on Rusty has the spot-weld at essentially the same point, but I can almost make out the 4th character as an E. Further, Rusty's pulley has the "C3" suffix. I say all of that to say I'm really confused by the parts catalog. But, I am confident that the desired pulley is a D00E-6312-C, regardless of what the catalog says.
And now for the before/after on the pulley Shaun sent as well as a couple of shots of Dad's original pulley.
Here's Dad's original pulley:
And, here are a couple of shots of Dad's original pulley.
It certainly did! And if I don't find the 460 serpentine brackets or if they won't work on a 400 I'll use it. May look a bit different since it'll be PC'd black, but it'll be the same pulley. Thanks again.
Midwestern is where I got the NV4500. I don't know if they still allow pulling your own stuff. I've been there twice, 1st time it was like LKQ. Pay a fee then find your parts and pull them yourself. The 2nd time, the trans was already pulled and strapped to a pallet, and they had employees pulling parts.
Oddly enough, those 2 trips were only a couple months apart......
That I fully understand. And, for that matter, I've just now healed up from picking up one end of Jason's 8.8, complete with springs, etc. Note to self: Don't put your ribs against a wheel well, get your whole body in an awkward position, and then pull HARD. Whatever snapped took a month to heal. But it's been six weeks so I'm ready to go again!
Sounds like you found some old armor plate. A lot of stuff uses an aluminum alloy armor. The mix allows for weight savings, meaning more armor for the same weight as a steel alloy or other, proprietary armor alloys.
My money was on it being an old chemical weapon warhead casing

No idea what it was, but this was back in the early 60's so the more recent aluminum armor hadn't been invented. In fact, this was probably WWII scrap as the plan had shut down at the end of the war.
But, having said that, I clearly remember and have a pic somewhere to prove, having seen a weld on a German pill box on the Normandy coast that had surely been done with stainless. Everything else was rusty, but this one weld was as if it had been welded that day. So, I guess I shouldn't think that all material science tech has been developed recently.
No joy in Mudville to this point, but there are several questions in this for y'all, so please read on:
Mid-Western
No 88-92 E250's or 350's
Do have two 93's with the 460 - Is that what I want but with the Bill's water pump pulley? What alternator mounting will that have?
Do have one 87 E350 but that would have v-belts - right?
East/West
Probably not pick&pull
Closed on Sat's
In fact, closed June 18th - 20th, meaning today, so don't know what they have
All Parts - Phone (918-587-6655) has been disconnected
North Yale - Nope, don't have any vans
American Truck
Nothing in the 88 - 92 range
Not open Sat
Have one pickup in that range
Have one '95 van w/a 460 - That would be Bill's large pulley, but what about alternator mounting?
He said "If I get a chance I will look at them"
Planeview
Not pick&pull, as they pull everything
Might have a serpentine setup but will cost ~$150
Open Sat 8 - 1
So, what is the chance that a 460's setup will work? I'm reluctant to spend the $150 on a remote chance. But, is there any demand for that setup such that I might be able to recoup some of my money if it won't work?
