New clutch or auto for puller

First of all wife is driving truck. She has little experience with manuals.
We just took F350 to its first pull. Wife got 250ft, then friend pulled it and got 280 (both in higher classes with 700900hp trucks). He says clutch was slipping towards end. It's a Bronco Graveyard HD. Truck still moves around fine, just don't think it will handle the power. I think there is some adjustment to linkage (haven't messed with one in 15 or so years). So should I get better/stronger clutch this winter or switch to auto. Did the switch on my F250. Have access to parts, no prob. It's just that an auto that "might" hold up is 3-4 grand. And I'm not familiar with rebuilders besides maybe Monster Transmission.
Truck is F350 in signature, ~625hp, D60/70hd, 4.10, 36" tires, T-18, NP205
Thoughts?

I don't know anything about pulling, but 3-4K sounds pretty steep for a built C6. Mine should handle 700+ but that's in a drag car. I built it myself and am into it about $1200 and then it'll be about $4-500 for a converter. That's with mostly stock parts.

What are other guys running in their Fords? Safety requirements? (Assuming there are other Fords where y'all pull.)

If you are serious about pulling with this truck and are making some power, stay with a manual trans and get a dual disk slipper clutch and a steel fly wheel. DO NOT USE A STOCK FLYWHEEL!!!!!!!!!!! I pulled for quite a few years so feel free to pm me if you want and I'll try to answer any questions you might have.

The motor makes about 625hp and the flywheel is a "40lb nhra" unit. Not super serious about pulling, but would like to pull a couple times a year. It's a street driven truck so I'd like to keep pedal feel somewhat low. Most street classes don't allow slipper clutches, but I've been looking at one that's dual disk and rated for 1000hp.

I'd be curious to know what you have to say. Pulling isn't popular around here so I don't know anyone who does it.

Does the T-18/T19/NP435 actually hold up? Their max torque ratings don't seem so high but if there isn't much in the means of shock loading I could see how they would survive.

Those 4 speeds should definitely be able to take it, just need a good clutch like you already know. If you already have the manual and like it, I probably wouldn't switch to an auto just for the sake of pulling. However, I have seen some good running trucks running autos. Not sure what all goes into a c6 for pulling, but I intend to find out because I plan on doing the same with mine with a c6. The trucks with the built up auto seem to have an easier time getting the sled moving without the boucing. They may not get as much power to the ground as a 4sp but from what I've seen, the autos are able to get on the throttle quicker with less bouncing and breakage. I've never pulled with an auto, but a couple of times with a 4 sp and hated having to slip the clutch that much

I've only pulled with an auto too, but when I was building truck I wanted to get as much power to the ground as possible. I hate clutch slip as well, but I'm gonna try it a little longer. I think I'll put the 1000hp clutch in and see how it does.

Anybody heard of or used a McLeod RXT Street twin clutch such as Summit pn 6921-03? Good or bad? I know there is one specifically for truck pulling, but I can't see spending $2000 on something to try.

I love this site and don't mean to try and take away from it, but it seems like it's not nearly as active as it used to be. If your on Facebook, ask to join the group 385 big block power. There's a few truck pull guys on there that may have some input for you. There's pullers here also but haven't seen them post much lately
