Thanks again for the replies guys!
The burnout video is going to have to wait until I get the 8 3/4 in it, I think any attempt at a burnout with the 7 1/4 will probably leave the ring gear laying in the street. Once the 8 3/4 is in I need to look for a dyno, would like to get the final tuning on the 340 dialed in.

Here's a few pictures of the interior as it is at the moment. I've still got a few things to clean up to finish up the fold-down conversion, then I'll get a thread about it up and some more pictures here.
