So one local is selling one for $400. Are they any good i have never heard of that brand before

 

I was doing soem search ont hem 2 days ago. They seems to have a very good rep on here. Check out the Drag racing or drivetrain forum and do a search for the specific thread. I also read that like Vig. converters, the company takes them back reconditions and cleans them for $100 to $200 to make sure you have a new quality converter.

 

i also noticed that ppl mostly have 9.5 stalls and this one is a 10.5 what does that mean and also what is the diffrence in a lock up and non lock up, witch one would i want on a everyday driver weekend racer

 

I dont know the complete answers, and I too am lost on the 9.5 inch and 10.5 inch part.

Lock ups from what I've searched, are what you may want if you will be going to the track. Lock ups are what I see most people get. Try doing a search on this. I did it a few weeks ago, and all of that was covered.
