I would go for the 3000-3200 range.

Thanks guys. I understand it better now. Should I still go with a 3000-3200 even if I supercharge it?

I say go with a 3000 it more streetable than a 3200.It doesn't seem like much differance but the streetablity jumps up alot when comparing the two.Not sayin a 3200 is'nt streetable...people do it all the time.But a 3000 is more practical.

If it's going to be supercharged I'd probably run about a 2800-3000.

OK, my turn for a dumb question. My current TC stalls at 1600. Suppose I get a 3000 stall TC. Now for WOT (i.e. at the drag strip) for any given MPH my engine will be turning 1400 rpm's faster. Therefore my transmission will shift to the next higher gear that much earlier, correct? And wouldn't my being in a higher gear for a greater % of the 1/4 mile negate much, if not all, of the gains made by launching at a higher rpm? I'm obviously not understanding something, but I don't know what it is?

You will launch off the line at 3000 rpms.After the truck starts moving from there it will gain mph as it should.You will lose a few mph in each gear.When i did mine i lost something like 1 mph in first gear and 2-3ish in second gear.You don't stay 1400rpms higher the whole time just because its a 3000rpm stall.Every stall ahs a shift extension some better than others...basically if you took a Yank TT3000 when you shift compared to your stock unit you should shift about300rpms higher than before.Basically like the yank site says...if you shift now at5500rpms from 1st to 2nd your rpsm should drop to 3300rpms.With the higher stall you drop to 3600 which gives you a boost into your powerband.It's hard to explain but trust me you don't lose more than a couple mph in each gear.
You basically stay in the trucks powerband better with a stall.You only lose a couple mph in the gears because the higher stall is a looser unit than that of the stock unit.Even still like i said its a very small mph.For me 1 mph in first and 2-3 in second.Thats not a very big deal when you consider you get off the line already in your power band rather than starting at 1600 and ahving to drag your truck up to 3000 plus to make some power.Then between shifts your making more power because of the higher rpms you turn instantly..

I think that was the best explaination that I've seen yet. Good job. More power into each gear holds you in the power band longer which gets you down the track faster correct?

What type of S/C are you going to get when it comes time.

MorepowerTY

Well I'm not sure. Some say Magna with intercooler because I live the desert, some say
Procharger. because you can make up to 150hp with it. Magna only gives you 120. But the question is, does the Procharger have a lag in it? And can the stock drivetrain handle it?

You will need a 3000-3200 stall for the Procharger because they lack on bottom end, but they pull like crazy mid to top range. If you go with a Radix you can run from a 2600-3000 stall because Radix are really torque and have alot of low end grunt.

But Prochargers with a 3000-3200 stall make to be some really mean set-ups that you can make alot of power from as long as you have a tranny that can take the abuse.
