If you are going to mod the car down the road, than a modular pulley system would be a good investment. That way you could put a 3.8 back on there until you do some supporting mods. If you are not going to do any mods, I am sure you can find somebody with an undamaged 3.8 they pulled off, and you can get a puller and put it back on.
You need to get that trans checked out. Where is Oxnard anyway? Edit: I looked it up....
