Can I get a /6 in the 7's?

My car goes 7.40's in the 1/8th. It's a no expense spared big block car. With a mild to moderate built 440 in it. It makes 310/450 at the wheels. 4:56 gears, 3500 stall. glass hood and a few other lightweight or lightened items.

N/A on a slant without seriously lightening the car. yeah, sounds tough.

Forced induction, I'd say you have a shot. But as said, unless you want to drop a ton of money to be "different" I might choose the V8 route. and you better have some serious skills or now a real builder/tuner who is truly skilled. That eliminates the buddy we all know who benchtop builds race cars after downing a 6 pack of beer.

Personally as far as wow and different, go to a car show and park a BB a-body amidst the others. Mission accomplished. Unless it's an exotic turbo or blown /6 no one is going to oogle your machine nor fear it.
