Help me pick a converter stall speed
Help me pick a converter stall speed A friend and I are puuting together a LS1 swap in a 87 Monte SS and I'm trying to pick the converter stall speed.
It's a LS1 with a mild cam with duration in the low to mid 220s, LSA will be 114 or 115. The car weighs 3400 lbs and has 3.73 gears. It will be a daily driver. We're not looking for something too crazy, I was thinking 25-2800 stall, but I'm not sure.

I'd go minimum of 3200, probably 3500 or so. A 4L60 lock up converter with 3.73's will be very drivable with a 3500 stall. Circle D, Yank, Vig, FTI, any of these shops are more than capable of specing and building a converter for you.
A good budget option for you is the 11" 3000-3200 stall. They are $375 with free shipping. Barley know the converter is there and a nice flash when you are playing around.
Another option with better performance is our billet street/strip series. They are $695 right now and would make the car very fun to drive. I would suggest a 3200 stall.

Some will recommend higher stalls then a 3500, but they have performance in mind (like drag racing or roll racing). But for a purely street driven car, the 3000 stall with a 2.0-2.2 will be your best bet. Both Circle-D and Yank can fill that bill easily and affordably. 
Thanx. Just courious what the performance difference would be between the $375 and $700 converter. I'm sure it's more expensive for a reason. We will definately spend the money if will make a difference.

Reliability, strength, & performance. A converter is not a place you want to go for the cheapest one you can get. It will have a big impact on the cars performance, driveablility, and will toast a trans if it lets go.

The $375 option uses the stock front cover and clutch. It is a 12" version so it will take some abuse. The $700 9.75" version uses a billet front and piston. So basically more parts to buy and machine. It is definitely stronger and will make a big difference in performance.

i am running a vigilante 3200 stall and it works very, very well for a daily driver car. i hear they are under rated. but after driving it awhile i think i should have stepped up to atleast a 3600 maybe. i just wanted a stall that felt and drove like stock.
