SChandler, and others....
I am gonna do the Burb swap
I found a 727 and rear from a truck, including the converter, flexplate, and lines for $600, less than 2 hours from here.
Now this swap, once completed is going to do some pioneering in 2wd pulling. So far there are literally a handful of guys doing it, some with VERY good results. The one I am thinking of is in FL and he has been gracious enough to give me some insite on what to do. This guy has been in the top 5 consistently, even winning against 4x4's.
Now when the pulling season comes along, the 4.10's are going in and they will be turning some type of MT 33" or 35" tires. But during the off-season the 3.07's are going to be swapped out. I know, a pain but that is what I get.
This will be also on a budget so the lockers are a couple of years away.
Until then....
Jon
