Tell me about the "wrap over"

Here are a couple pics.  I think I have a TWM TB that will work with it, but they aren't cheap, and I'd have to do some searching to recall what size and bolt type it is.  Atkins sells a straight intake, and this wrapover intake.  If you've got room over your engine, this isn't a bad arrangement, but you'd want to do some work to make the ports match better, particularly for the 4-port. 

I'd sell the intake for $100, and I might also sell the throttle body, but I'd have to figure out how much I paid for it.  I know it was pricy.

Cheers,

Rusty (unable to put off the agony any longer)
