Snowman,
Yes, 4v means 4-barrel.
Well ok, if you don't want to go the turbo route, the other top combo that Tom Lowe plans to dyno is a 250 with a barely-streetable cam and Webers. I do mean streetable, I ran a cam that wild in my old 2-liter Pinto of all things. It was liveable, at least in Northern CA. Not sure how it would be on a sub-zero NW Illinois morning though.

So I gonkulated the cam+Webers combo in your car, with a 4.56 gear and the T-5:
14.32 at 95.5.
Once again it will be a close race, but you'll need the 4.56 gear and T-5. And, I bet the Weber setup would be as pricey as a turbo, since you have to build the 250 either way - to survive the turbo pressure, or to survive the 6500rpm shift points of the Weber combo. It is just hard to get a 250 to keep up with a 400 Stage 1 in the same car body!
