Welcome!
I replaced my totaled 89 SHO with a CSVT. The car is much more refined and the handling is far superior, but the SHO engine was a thing of beauty. It has far more torque than the SVT and revs nearly as high.
The Duratech in the SVT and other V6 Contours is of similar design to the SHO, with DOCH and long/short intake runners. The secondary runners open just below 4k on my SVT.
I plan to clean up the y-pipe soon and maybe I will find some more HP.
The SVT avlready has a cold air intake. Most of the aftermarket CAIs have the filter behind the battery, which is warm air at best.
