Default Is 2800k Stall Gonna Do It?

Precision is telling me to go w/ a 2800 Stall??? I figured at least a 3000k, I wonder if its too much
I'm told the 2800 will take better advantage of my power curve. Seems most of you guys are running 3000-3600k.
Another Mfgr. recommended a 3200k w/ my setup. I'm just not sure?
I'll just go 3000k (middle of the road) unless I am convinced otherwise, thanks guys.

- 4l60e
- 4700lb truck
- shifting @ 57-5800 rpm
- 3.73 gears
- 31" tall tires (street)
- F/I (supercharged)
- stock cam

What kind of supercharger do you have, that will make a big difference in what kind of converter you should go with. Im guessing a BD-11 is some sort of centrifugal s/c if so then I would go with a 3200 or 3600, 3600 will be good for when you put a cam in later.

centrifugal yes. Its my understanding that stall should be approx. 500-700 lower than peak torque and with most of these engines (lm7) peak seems to be @ 4000k. So now, 32-3500k seems more realistic to me. I also thought about the cam too, not sure when I'll do that though.
Thanks man. This whole f-ing process is making me I hate making a choice like this without feeling or seeing the results first.

your shift extensions are going to suck with that low of shift points and that 3k converter.

Makes sense. Main reason I'm not shifting any higher is to avoid over clocking the S/C with the 11lb. pulley and stock Crank pulley. I guess it might be better to drop back to a 9 lb. pulley and move my shift points back to 6k (or rev. limit) for better overall performance? Thanks, I hadn't really considered "adjusting" my power curve in that way yet. Correct me if I'm missing the point here. it's 4am I'll check back later.
