Robert, you can easily drop the front of the motor by an inch and the tranny mounts will barely have any deflection. It's the geometry of the mounts that allows this. Go slow and you won't have any problems.

Maybe I'm missing something but I've got to ask. Recently when I swapped out my stock TB and intake plenum (only the TB housing, not the runners) I measured the entry diameter of the runners to be 3.5". This is on a 2000 base box with 2.7. Because of this I didn't even think of doing any further modifications because at that point the TB was the point of obstruction and I'm obviously not going any bigger than 82mm there. Quadcammer mentioned 73mm though? Where is that measured? I saw the pic above comparing the two side by side and the 996 do indeed look a bit larger but again in terms of fluid dynamics my question would be if this is truly meaningful or if the real money shot is enlarging the narrowest point (in our case, the TB) to ease the point of greatest resistance. My understanding of fluid dynamics as it applies to intakes (and trust me when I say to not trust me!) is that in general the intake cross sectional diameter will taper closer to the heads and thus create an increase in flow velocity which aids in filling of the cylinder volume without creating a single point of significant resistance. The key is to start small and gradually shrink, whereas with our stock setup it seems to be exactly opposite of this (tiny ass intake, restrictive TB, and then relatively big but really a bit undersized runners)

Anyway, just random thoughts while taking a deuce at 11pm on a Saturday.
