OK guys, so I'm getting almost done with my LQ4 swap in my 68 camaro. It has LS3 heads, a 222/230 cam with .570 lift, ls3 intake, etc. I am expecting it to make somewhere in the neighborhood of 400rwhp or so, and am going to have it professionally dyno tuned up in West Palm by masport.
Here is a link to the build threat:

The idea is to have this thing be a daily driver, and I'm serious about that.
I still obviously want it to be fast as hell. I might go to the drag stip once or twice, but would be happy with something in the mid 12s.
It has 3.42 rear gears with a 9.5" GM 14 bolt (made special), and a 4l80e tranny.

It also has the STOCK converter. I was thinking that with a street driven car, a stock converter would be appropriate. What do you guys think? Keep in mind that I drive about 15 miles to work each day and about half that time is highway. What would the effects of a higher stall be? Wouldn't the higher stall break traction off the line easier? Would it make it more difficult to cruise or function as a daily driver? Thanks guys.

I think a mild stall (3000ish)from someone like Yank converters would really wake it up.
I don't think a "stock" converter will live long under a heavy foot with a modded motor.

With a street/strip car there are always compromises....go fast and lose some streetability or streetability and lose some performance at the track ?

What is considered stock stall? Reason I ask is that you will be leaving a bit on the table without upgrading the converter to something say 2800-3500 range. If you go with something much more than that than you are really going to be putting a lot of heat into the transmission just puttering around. I have a restalled stocker ~2600 to 2800 stall and my cam is bigger...not too much bigger, but it is. I would not be at all surprised if you rip and 11, assuming you can get it to hook.

I have a 68 camaro LS1 with 224 TSP cam and am running a 3200 stall and stage two shift kit and it is very streetable. The only time you can really tell there is anything done to the transmission is when you get on it.

My combo, in a 55 Chevy sedan: [A street car w/ an occasional track trip.]
LQ9.. Mild cam, CAI, dual exh using truck manifolds, truck intake.
W/ the 4L60E low gear, I chose a 3.50 ratio.
I currently have a Trailblazer converter. It stalls about 2/2100, B4 the brakes allow movement.
We just completed another install using a 3200 stall...Kinda loose at low rpm, but works well, as it's in a 4L80E, 3.50 gear, and a bit heavier car. [60 Impy]

If I was doing it again, I'd opt for the 3K stall unit.

I am getting ready to buy a cam that is almost identical specs to the TSP 224R. It was recommended I use the stock converter, or if I buy one stay in the low 2K range since this is where the torque curves begins....so basically match the stall to the operating range of the cam.

Ok. So what converters would you guys recommended?

I have a Circle D 245mm 2b 3000 stall converter with roughly the same cam you have. I am getting 1.65 60' times and the car drives excellent on the street. Also, I was thinking mid 12s when I built my car too and that turned out to be 11.70s. So be prepared to be very surprised how fast your car will be.

Not an LSx car but my tpi swapped 81 elky ran a b&m 2800 stall converter daily for years with no decrease in mpg and actually similar traction characteristics off the line. Do it!

With that mild CAM.. 2600-3000 is most likely recommened by the CAM maker.. you should check with the CAM vendor to see what they recommend for your setup and type of driving.

If you are daily driving it. I would keep it under 3k... with lockup and you might not even notice the stall..
