I would need more details on your truck to give you an honest opinion on what would be best for you. However like you said a built 60 is still more than doing the 80 and the 80 will be stronger IMO.

There's a lot of good advice here. I didn't really wanna fool w/. an 80E swap, sourcing a core, adapting wiring, & other hard parts I'd need. Alot, & I mean alot of guys were (& are) running fast & hard, & 60e's were their trannies. I didn't say they hadn't blown their fair share of 60e's up tho. To the OP, $2500 is a bit to save up, & it took me a lot longer to save up for my tranny than I thought. But I also bought a stall at same time. It seems I can never just put only 1 part in. I always do the, "well, while I'm in there, this would be a good time to ...". It inevitably adds cost & time to any given project.

Also, not to turn this into a who builds better thread, but I'd seen success coming from a particular builder, & their 60e's seemed to do the trick for many, so I'd give it a try. If it didn't work & blew up, well ... I really couldn't afford another trans (either a stock 80E & what it takes to make it work or another built 60E), so I was relying on the record of that builder. Otherwise, I'd be in a real bad financial situation, so only 1 trans had to fit the bill. Thankfully, I made a good choice.

Had there been, I probably would have went that way myself. Never-the-less, I’ve never had a minute’s trouble out of the 65E. I go to the track every once and a while, and I run it pretty hard all the time, but I don’t go around beating on it like a redheaded step child at every stop sign either and is most likely why it’s lasted me so long. Even my factory 65E lasted over 5 years spraying the 6.0L with a 150 shot, and when I pulled it, it had just started flaring on the 1-2 shift. That said, now that there are options available, I may go ahead and make the swap, but if the economy doesn’t improve for me, I may just have it freshened up when it needs it and keep rocking on. At this point it doesn’t scare me to keep running it.

I do agree that if you’re going to be spending the money anyway, you might as well go with the strongest option available.
While I run mine hard on the street, I don't make your kinda power. I also only go to track maybe once a month. Two times a month, then I may take a month off. So, say 4-10x a yr. I take it to track. I also run street tires, no slicks. But that may change when blower goes on, but I still wanna go once a month.

One of the things about the 80e is gas mileage, if you care about that. It just seems to kill gas mileage. I guess one of the reasons is that the stock stall is significantly looser than a stock 60 stall.
Yes, but a 6L doesn't help or 4.10s. IDK what killed my mileage the most, my stall or cam, since I did them in the same yr. And RFG or other issues (cause I know I have an issue) isn't helpin me, all on a 5.3 w/. cam. I'm getting 10MPG in winter. This summer we'll see how bad stall & cam really hurt my MPG.

As Beatdown Z said, it was already overwhelming enough. An 80E swap would have drove me insane at the time. Plus

Like Rhino79 said, a 60 takes less power to turn.

It weighs less too. And it has a nicer 1st gear & OD is better for mileage.

I installed both myself. Yes, I ordered the stall at same time as tranny, & yes u can send stall to FLT if u wish. The beauty of that is, FLT knows your stall works, cause it's on their machine. My convertor was accidentally sent to me by mistake, but Chris made it right & picked up the shipping, & it was sent to FLT. They (FLT) can use a house convertor to run your tranny thru testing tho if u don't want a stall or can't afford one. It's just better to send to FLT rather than install in your truck & it not work.

No problem. Chris at CircleD & the fine folks at FLT were (& are) great people to deal with. I think you'll be pleased if they get your biz.
