Your idea about joining the 2 plenums opposite the t-body has been discussed at much length in the past. Sorry, I don't recall what title it had but the discussion went something like this. To do this mod properly you must incorporate a valve which can open/shut at XXX RPM's. Someone chimed in who had prototyped such a system on the original Duratech and there were NO gains with it. I don't have a handle on the search thing but this topic is from 2001, if you want to try and find it.
I'm going to do the lower install first and butt-dyno test it. Then I'll add my t-body spacer. If all goes according to plan the lower will be on this weekend.
