Joe.....I just noticed your short video a little while ago. It is very telling. I believe you said (and it sounds like) you are starting off in 2nd gear. That sounds painfully obvious by the big drop in RPMs each time you shift. And, that is another trait of the "suck-ass" gear ratios of that "S-10" transmission. The ratios are just spaced too far apart to keep the revs from falling drastically each time you shift.
We know that your 4.03 1st gear is worthless. You're starting off in 2nd, which is a ratio of 2.37 to 1. With that 3.25 rear end, that's a pretty stiff overall ratio of 7.70 to 1....pretty damned steep. If you had a close ratio Camaro-type 2.95 1st gear along with your 3.25 rear, you've bumped-up to a 9.59 to 1 ratio....a very comfortable range for a performance 1st gear ratio. And with the subsequent 2nd, 3rd ratios of the close-ratio gear set (Camaro), the RPM drop between shifts is much less, keeping the revs much tighter in the power band all the way through 4th gear.
It's very likely that your 5th (OD) gear is a 0.72 ratio. I believe you've said that it felt like 5th gear was lugging the engine down. There is an available 0.80 5th gear in a Ford T5, but it MAY be difficult to find one of those "used". I'm thinking that an .80 OD would probably be just right for your set-up, even KEEPING that 3.25 rear gear. I'm sure that you would rather NOT need to be changing the rear gears. So, here's what I'm thinking you might consider.
I would start building a replacement trans exactly the way you want it. There are a lot of ways that you can do that. Keep in mind that there are MANY T5 parts sources on the ol' interweb. Lots of parts on eBay in particular. There are T5 specialists around the country, but not many of those giving bargain basement pricing. They can be a source for that one special piece that you might end-up needing, though. Don't forget the likes of Craigslist for complete transmissions.
I think I would attempt to find an '88 or later World Class Camaro V8 (gotta be from a V8 for the 2.95 gear set) transmission. That SHOULD match the bolt pattern on the front of your current case. Unfortunately, that trans is going to have a .73 OD ratio, essentially what you have now. There is a Mustang 5th gear-pair which will yield an .80 OD ratio in a close ratio gear set. The small gear is 20-tooth, and the large gear is 32-teeth. But, the small gear is of the 28 internal spline Ford-type (whereas the Camaro SMALL OD gear is 27-spline internal). You would need to go on eBay and purchase a separate Mustang-type 28-spline, WC (World Class) main shaft "used". They normally don't wear out, and it fits with and replaces the Camaro shaft just perfectly. You would also have to swap your drive shaft yoke for a 28-spline Ford yoke. But, you'll have one very fine, and I believe perfectly-tailored 5-speed that you're gonna love once you row through the gears a couple of times. Just so happens that there is an eBay vendor that currently is listing his last set of heavy-duty ".80 to 1", WC Mustang OD gears for a steal of a price. Those normally went for I believe $263 from another T5 specialty outfit. Try this link below! If the link doesn't work, it's eBay Item #173985041792.

That's about the best advice I have to offer. If I can help, hollar! DD
