More than remotely- I've seen a few supercharged straight sixes, two of those being Hudsons. I doubt it's very practical, but it's a model, so I don't need to worry about any potential drivability problems in my case.
The clear hood always fit better for me- if you painted the clear custom hood body color it gave the car that totally smooth look that was oh-so-trendy when I first built this kit in the early '90's.
No. Only the small block SS and (I think) the Yenko have buckets. The COPO only has a front bench.
EDIT- NEVER MIND!
The COPO does still have the buckets, they just aren't mentioned or shown on the box. So I stand corrected there...
