    I know it's apples to oranges (old 350 vs LS based), but my truck cut better 60ft times by power braking to 2000 on a 2500 stall converter.

    I wish I could find my time slips, so I could be sure...

    What is important here is you will have to try all options out out see what works for you.

    Well I did some launch's after work on the way home. When I stall up the truck feels like it's sluggish. When I just floor it, I get just a little wheel spin but don't seem like it bogs down as much. Their is only one month remaining until the track closes for WINTER. Hope I can get down to the track for true results.

    Your launch rpm depends on your mods and motor setup. Like Allen said--a FI launch is different than a N/A launch--to a point. Same thing with Brad's truck. A turbo and S/C will have different stalling techniques. You need to put some track time in to find out which style is best suited for your setup....
