Will the serpentine belt system from a newer 460 work on my 429? I am doing a swap into a 79 Bronco and would like to use the serpentine belt but don't want to spend the money on a kit. I am hoping to find a newer 460 at a junk yard to get parts from.
I just did this upgrade when I put an '86 V-belt carbed 460 into my '66 F-100.
What year is your 429? If it is an early car engine, then you will have an issue with the bolt holes in the heads. The aluminum serpentine brackets will use a larger bolt, but the early heads (before D3 heads, I think) will have smaller bolt holes. Since the bolts take a lot of stress to hold everything in place, you'll need to turn down the threads on the bolts just right, so that they seat all the way, but don't lose strength holding the bracket in place.
Brackets: I ended up buying new both the left and right aluminum brackets, at $120 and $90 from Obsolete Ford. The boneyard ones were cracked and corroded, but I got all the bolts and other parts. Well worth the money. Make sure you get the driver's side bracket for a truck power steering pump (the round wide-mouthed plastic cannister), not a van (the teardrop shaped Saginaw pump).
Alternator adjusting bracket: You'll need to get the right one, whether for the larger or smaller alternator.
Pulleys: You can replace the v-belt pulley on an alternator with the serpentine one if you also replace the fan.
You can do without the smog pump, unless local codes mandate it. Just get a shorter serpentine belt.
You can replace the A/C compressor with an idler pulley, or you can just use a old compressor with good clutch bearings.

The sad part is I have run into the guy that has the other brackets from the same motor and he has yet to come off of them and he even told me he didn't or doesn't need them. I had to dig through the scrap pile because they tossed this one bracket away for scrap.
I also had one person tell me $800 for a set. This guy must be crazy because one could more than likely buy a new set up from ford for less than that. I have contacted two other people that said they would sell the brackets but haven't gotten anything yet so I'm searching myself.
Guys, I bought the right bracket (power steering, A/C) from the Ford dealer for $89, and the left bracket (alternator, smog pump) for about $120 from Obsolete Ford parts, and they weren't the only ones to have it.
I salvaged the water pump pulley, crank pulley, alternator pulley, A/C compressor, radiator fan and clutch, tensioner, and alternator adjust bracket from an '87 van with 460. The power steering pulley I had to get from a '92 Bronco with a 351W (5.8L) with a single belt serpentine, and I think the tensioner and alternator from that Bronco will fit my 460. (The van PS pulley won't fit a truck PS pump. See my previous post.) The Bronco smog pump and pulley will fit the 460, but I am not using them. All the parts cost me about $50 at the local Crazy Ray's U-Pull it place.
Crank pulley – E7TA-6312-AB
W/P Pulley - E7TA-A8509-AC
A/C Idler - E7TA-19A216-AB
(used in place of a/c comp. if no a/c)
Left bracket – E7TA-10239-AB
(Forgot the right bracket)
Alt Adjust Bracket – E7TA-10159-BA (Not available from the dealer or from Obsolete, at least that was true 6 months ago.)
As for the bracket bolts and turning them down, I THINK you only need to turn down the ones which bolt into the heads, IF you use a later water pump. If you use an earlier pump, you'll need those bolts turned down also.

I'm not familiar with the older heads, but instead of turning down the bolts, couldn't you drill & tap the heads to the larger bolt size? Just a thought, as long as there is enough material in the heads and you don't care about keeping them original. I would think this would be the strongest way to set it up if it can be done. Again, I'm not familiar with these heads, so check before you drill!
I forgot to mention this in my first post. Don't most serpentine belt systems turn the water pump the opposite direction from the crank? If this is the case, I would thing you would NEED to use a late model pump. I have V-belts on my 460. Maybe someone with a newer 460 can confirm/deny this?
The Windsor series motors do indeed use a reverse-rotating water pump and radiator fan, because they use a single serpentine belt.
However, the serpentine sysem I used has two belts, and only one is serpentine. The other is tensioned with the alternator in the usual fashion. I believe this setup was used from '87 at least until '92.
I do not know if the 460 ever came with a single belt serpentine system. If it did, I do not know what year that started.
As for tapping the bosses on the heads, I am told the boss on the earlier heads is of insufficient size to allow a safe increase.
Ah, ok. Well, that's why I said check first. I wasn't 100% sure. I do know that the 87 460 was still v-belts. I have one in an F250. My guess is the serpentine belts came into the mix with the fuel injection in 88.
Yep, sounds like typical Ford engineering!
I have several serpentine components from an '87 van with a 460, one or two from a '92 Bronco with a 351, and some from a truck with 460.
Looks like some factories were still using V-belt components in '87, as evidenced on your truck. Or, could yours be an early '87, produced in '86???
If you will notice the parts list I posted, all the numbers are E7 design numbers.
"E" specifies the decade, which means 1980s; "7" specifies the year - 1987 in this case.
These numbers do not specify the year of manufacture, but the design year. For example, in 1965, Ford introduced the Twin I-beam suspension. The radius arm bushings carry a "C5" number, indicating 1965 design. If you buy these bushings for a 1979 or earlier truck, you will get parts designed in 1965.
