Fan clutch recommendation
Hi all!
I usualy post in second gen or ram van section but I am helping a friend who is restoring and customizing a 1979 trans-van with a 360 LA motor with a 46RH 4spd trans ( overdrive and lock-up will actuate manually).
I need a recommendation for a heavy duty fan clutch, if this was a magnum it would be easy as I have an extra V10 truck fan and clutch but it’s an LA 360
does anybody make an adapter to mount a magnum fan clutch to an LA motor?
just need a good functioning heavy duty fan clutch
anybody?

Aftermarket fan clutches seem to be junk, I had a few on my trans van when I had the la engine and they just didn’t work right, older trucks, if you can find them would work great but it seems most have been changed out for flex fans or after market
just wondering if anybody found one that works good

All the LA motors i had(with the exception of my 90) had flex fans. May want to get a electric fan. I would look up the part #'s for what was used on the heavy duty engines that where used in large vans/winnebagos/police cars etc. May also look to see if the fans where different. Either way these will have what you are looking for. Then cross reference the #'s.

Flex fans are very dangerous!! Period
maybe newer ones are made better but back in the early 80s they would fly apart after awhile of use. All the hot Rodders would use them, it was the thing to use on a high performance engine. I personally had one fly apart and go through the custom L88 fiberglass hood on my 70 camaro!! After that day, I refused to use one and allways took it off a car I would buy! Just too dangerous

Well you needed to keep an eye out for cracks, If you see one starting stop using it! The ones i used i bought new and never started to crack. But ones i got with motors/cars would have small cracks and they went right in the trash. The good and bad: good is they pull air instantly you don't have to wait for the clutch to heat up before it locks up. Bad even though the blades flatten out at higher rpms it still creates a bit of drag on the motor. You may want to look around on the Hayden site, I found a clutch for a Diplomat with a 360 heavy duty #2747 Also did a search for a 79 New Yorker with the 360 and that # came up again.You can also call their tech line.

Don’t trust Hayden got one before when I had the LA engine installed , it worked but it started to leak after about 1500 miles
most of the after market are made in China, some work some don’t
I was thinking of getting a buddy of mine to make an adapter out of steel, it will bolt up to the water pump and have the threaded part to mount a later fan clutch, then I can use the heave duty ones from Chrysler just don’t know if an early water pump can handle the torq

Stay away from flex fans with aluminum blades. I also had one try to rip through my hood (on a 69 442). The steel flex blade fans are fine.
I converted my 85 d100 to electric using a oem replacement fan for an 06-up PT Cruiser. This is a two speed, 17 inch fan that is installed on a 40 amp circuit. It comes with a harness and two standard relays for $40 on ebay. Most aftermarket universal electric fans only pull about 10 amps.
The fan and shroud was a perfect fit but the fan molded-in brackets had to be trimmed off. I left the shoulder of the top and bottom brackets so the fan could sit against the aluminum core end tank flange so it can't contact the core itself. I made new brackets from .080 aluminum sheet that attach to the radiator with the original shroud bolts and to the fan shroud with three #10 machine screws and large washers with lock nuts for each bracket. I used a toggle switch for one speed manual backup and a universal thermal switch (200-on, 185-off with 180 stat) for automatic cooling, two inline fuse holders with 20 amp fuses to the battery, two thin blue control positive wires from the fan to keyed power so it only runs if the engine is running.
Still running the original dual vee belt alternator but the output is a 10ga running straight to the battery (made a distribution /isolator post mounted next to the battery using blue rain barrel scrap hdpe and standard hardware). High output, dual vee alt is available for about $80 but requires wiring upgrades.
