The reason i'm not doing a top swap is because i personally would much rather swap the whole engine rather than do all the work of the top swap. I've pulled L67's before and it takes me a couple hours to get them out. Where it would take me alot more time to get the top swapped and the rest finished. Just a personal preference. I'll have to see if i can track down a vacuum tree or a diagram to build one. As for the BBV i may need more info on that if anyone has it so i can figure out what i want to do with that aspect of it.
