dumb stall question
What size should I go
What does it do exactly?
How does it help your times? I know im retarded.
The three standard recommendations are a Vig3200 (stalls higher), TCI SSF3500 and Yank SS3600. Search and read about them. You could go bigger and get something like a vig3600, yank SS4000 or TCI SSF4000.
Will you be upgrading your rear end or gears?
Search should answer your other questions. Try howstuffworks.com as well.
A high-stall torque converter increases performance in a couple of ways. The first is the obvious one in that it helps you off the line via its higher stall speed and increased torque. The other big advantage provided is what's called “shift extension.” With a high-stall converter when your transmission shifts at WOT, instead of the engine speed dropping down to 3000-3500 rpm, it will stay at 4000-5000+ rpm (depending on the converter) and you'll be right back up to redline again for your next shift. This results in your motor staying in the meat of its power band for the whole run and that translates into improved ETs. This “shift extension” factor will help even if you never visit a drag strip, as it will eliminate the “dead spot” that stock converter cars suffer from. Now, when you accelerate and your transmission kicks down into passing gear, instead of your engine having to build up speed from the 3000 rpm range, you'll be starting at that higher engine speed which translates into better acceleration, better performance, and safer passing.
Like at the line would I hold the gas near the stall height when I go to take off?
Yes, it will make traction off the line more difficult, but you'll be quicker if you do stick. Steeper gears take some of the looseness out of the converters as well.
