Well, there certainly is plenty of room to do about anything like that
if I wanted to.  The problem is that for right now, the engine bay needs
to at least look 'normal' because I autocross and street race this car. 
At least I could stick a SuperRam on there if I wanted a big plenum in a
bulky package, and that requires only minor fabrication to work with the
LT1.  Just about anything else is going to be built from the ground up. 
I might go there in the future if I have time for that, but for now, the
important thing is to get it running, and I thought it would be easy to
add on to the OE intake.  In fact, there is nothing on the top or rear
of the plenum except space, so I could really add all I needed if I
didn't care about ugliness.  Would be fun on the dyno to see what it
really wants.

Later dates.
