/6 or v8 swap?

I have had everythng from the slants to 426 hemis, maxie wedges, and small blocks in between. I love driving my slants bone stock, but yep slugs. I just lke to cruise down the road in them. A good teener an get just agood mileage. I have had 833 OD slants get 25. Best by far. But a stock SB has never interested me much except the 4 speed AAR's I had. Prefer the torque of a good geared 383 over them all really.
I really have a feeling your wife and you will prefer a good sounding, running SB with a gear that keeps it interesting.
The turbo would wake up the slant and costs some $$$$ too! Good luck!
