I have tick recommendations but it just seems high I put a 3800 stall in it and it screams around town and smokes the tires when converter locks in. Don’t get me wrong it is fun but seems to me a 3000 stall would be better suited. Thought maybe someone has same setup as me and can give me a recommendation

Get a set of radial slicks and good to go

If it were me I would get rid of that loose, inefficient converter and get a Yank or something comparable.
Something like a SS 3600, SS 4000 or PT 4000. They will all drive soooooo much better than that tci.
If you are looking for performance then yes, there is a big difference in those stall rpms

I had a TCI that was too loose everywhere.
I called a very well known company and they made a converter for me, they missed. It was just like the damn TCI except billet and $800+
Then I called FTI and they made one exactly like I wanted it. tight around town, damn near exact stall speed at wot.
So....not all 3800 rpm converters are loose around town.

I spoke with tci last week they said they could tighten my converter up and lower the stall to around a 3000 was quoted 175-250$$ to do the work. I have over $500 in converter already had to spend another $800 for a yank

69, I wouldn't spend good money after bad with the TCI. Call FTI, Yank or Circle D and have them spec a good converter for you. I have a 4000 rpm converter from FTI and it has good street manners as far as I'm concerned and when you hit the gas it makes a huge difference over the 2800 - 3000 converter I had before.

I always thought TCI had good reputation I didn’t know they where so disliked by the LS car crowd. I always used them on my older sbc. That’s why I bought this one
