Of course, Mr. Dunnington. Please excuse my logic lapse ;)

I have recently been exposed to this setup in a roundabout way(Pontiac
4.9l). My concerns about this configuration have been packaging ones, i.e.
height vs. hood clearance. The GM compressors for these applications have an
interesting 90deg. flanged outlet that looks to offer more packaging
flexibility than a standard outlet. Tough to tell from the pics I've found
so far if that outlet adds any height(a bad thing), but it has a little
horizontal offset that could be a very good thing. So far I've not been
sufficiently Google-talented to obtain any a/r or trim data for the GM
compressors. They are T-03's, but I strongly suspect the compressor housing
a/r is larger than desired for a 196. On the relatively low-rev'ing 304 in a
pre-'69 full size(lot's o' hood clearance!) tho'...... 8P Heck, I've got a
266 in '66 Travelette that *really* wants to be a 392, but *doesn't* want to
be as thirsty as a 392 most of the time :)
