I also cut 1.69 60fts with it with nothing but summit rear drag shocks, lca relocations, !front sway, and 275 Nittos in a stock LS1 with a lid, catback, and 3.73s.
One of my friends was in the upper 1.5s with an SS4000 with a lid, cutout, and tune with stock 3.23s.. but i had quite a few mph on him.
We're also 2500-3000DA all the time, so to you sea level guys thats probably not impressive

How many rpms would this stall tighten up for the street going from 3.23 to 3.73?

Hey Senical, I have a ss4000 in my car. I drive it every other day to work. I have the stock 3.23 gears. The car starts moving at about 2800-3000 rpm in city driving. Once you get to about 40-45mph the converter locks up and you dont even notice you have a stall. You gas milage will suffer a little bit. Meaning it takes a lot more throttle to moves the car in traffic and you wont be able to keep your foot out of the gas. DD with this stall takes getting used to. Make sure you have a good tune along with the stall. You will also need some sticky tires. Mine spins like crazy when I hit the pedal.

My buddies 273 ptc 4000 car only takes around 2200-2300 and I will bet hits harder than that yank.

If i went 3,000 RPMS with my SS4000, I'd start passing up traffic.
2,500rmps to keep up with traffic is more realistic. Going up a steep hill at 30mph would take 3,000 RPMS.
It's really not that bad, there is a reason people still put these in their cars. Mine is also programmed to lock at 30mph in 3rd and 40mph in OD.
Keep in mind i have 2.73s, RPMS could be a bit different.

The gear makes a huge difference. with 3.73s/pt4000 1500 would get it moving, 2000 would keep up with traffic, 2500 would pass traffic, 3000+ would blow them away. Passing cars giong uphill it's not uncommon to be in the 3000s. The highway "passing gear" is amazing with the stall, even with a stock motor, and it's much better with a suitable cam.
Heres a video showing 3.23s with pt4000 in typical driving conditions, and some wot runs.

Its much tighter than that with 3.73s.

No, that's not mine, I don't think I ever got a video of mine, I'll double check.
On the highway, you're talking a 500rpm difference max. IIRC with 3.73s and 26s i was at roughly 2500 going 70-75 when the converter was locked up.

Here's a video I had from racing the car from a slow roll.
My maroon Z28 was stock LS1 with lid, full exhaust, 3.73s, PT4000, and 275 Nittos untuned
vs
LS6 WS6 with fast 90/90, full boltons, underdrive, 3.90s, 6spd, 315 nittos made 420rwhp @ speed inc
Chase truck is a maggied 5.3 RCSB 04 Chevy, 4wd, lowered on 18s.. went 13.0s in 2500DA lol
A stall is one of the best first mods IMO.

I had a 408ci street car with a 4500 stall and 4.10s.. If I wanted fuel efficiency I'd be on Honda forums

The Yank PT4000 is a very loose converter and 3.73 gears will definitely help tighten it up, but a 4000 stall is still loose. I ran one for a few years and switched to a Circle D 5c which is actually tighter on the street, hits harder out of the hole and slightly more efficient on the top end. The PT4000 has a relatively low STR and works best when launched slightly above idle and has a high shift extension which is why it's so good from a roll. It's still a good converter, but on the loose side especially after break in.

Damn. Thats manuals making about 100 more hp than you. Its hard to see very clearly but it didnt look like he beat you all that bad. What was the mph roll to finish?

75? lol. Watching that video of the 3.23s made me realize how much of a huge difference there was between that and 3.73s. I put a cam in the car and drove it to texas speed and it still made mid 20s on the way after the tune.

I could give a **** less about mpg as well, but some of these guys on here it means a lot to.

Indeed, I was curious what you were saying 75 about?

QFT. I've never had the pleasure of owning a Circle D, but I've heard nothing but good. I tried to get them to build me a custom stall for my 408ci car but I ended up finding a smoking deal on a Yank 4500 so I went with that. They are quite pricey, but from what I hear worth the cash if you can swing it.
He had me by about a car at 120, I let off a bit then hit the brakes and he kept going for a while. We raced several times, if I would spin he would edge out 2 cars or so, if he'd spin I'd edge out 2-3 cars. Every time we both hooked it was the same result.
