bad boy 273 cid why not

Yeah, been there done that (but not with a 273).

In my experience you're better of with the 360 and going 11s instead of 12s for the same money.

Nobody is going to get hung up on being beat by a 273 any more than they would being beat by some other V8. So, you're better off being able to beat more people by going 11s instead of 12s for the same money.

Also, when you want to sell the car, an 11 second car sells easier and for more money than a 12 second car.

And, on a single run, 11s are a lot more fun than 12s.
