I was planning to pull the transmission to install downpipes and fix a rear main seal, but not pull the plentum at this time. I'm not sure how much of the block off I should do from below, and how much to leave until a future plentum pull. I guess I could do the entire delete with the plentum pull, I've studied BradZ (FL)'s post on this, but it seems like a wasted opportunity. Thanks again.
