I was reading old threads online and it looks like most people are running the speedway 91628908 adapter plate for the ls swaps. The plate is currently on back order and I am wondering if anyone has tried a different company for an adapter plate. I am putting my parts list together and taking the dive into the LS swap soon. I have a lq4 and a BOP th350. If anyone can point me in the right direction I would appreciate it.
