the last thing i need to buy is a torque converter, for my 4l60e. my setup: a forged 383 lt1, i will shift a 7k. slicks, 3.73 gears, stage 4 4l60e, car should be 3200#s w/me, full suspension mods. i sold my tci 3000 converter. which one should i buy? 3600 or 4000 stall? im shooting for low 1.5 60's. thanks.

 

I would go with a 4000.

 

4000 for sure. I have a 3600 on medium bolt ons and i could really go to a 4000. With your mods definitely do 4000.

 

Any stall you like!

I'd go with a 4k as well.

 

now there's a deal right there!! saves over $200 bones!! but yeah 4000 gets my vote

 

You have a pm sir

 

Correct me if I am wrong, but I did not think the ls1 and lt1 a4 were interchangeable?

 

the car is an lt1. thats why i wondered if 4000 was too loose or not. also what brands are you guys running? i was looking at the yank ss series.

 

Not interchangeable.

 

Yank SS4000 gets my vote.

 

Well I'd like to know what the torque curve of this combo looks like. Bigger isn't always better, picking out the right converter is almost as hard as picking the proper cam. Do yourself a favor and call an expert.

 

Circle D 5C would be killer for your set up. Chris will custom build it for your LT1 set up. You won't be disappointed.
