is this a good deal?

If you want a challenge, why dont you try stuffing a Hemi in there - lol.

As far as the 6 goes, well, I'm not a fan. You will just wind up spending a lot of time and money on something that will give mediocre results and will make your car be worth less in the end.

Now, if you could somehow put two 6's together, side by side, then you may be on to something - lol.
