Oh boy I want to go fast

It doesn't take a 408 to run 11s, and if your suspension isn't set up as well as your engine all you're going to do is make tire smoke and spend money.

I'm running mid-high 11s with a junkyard shortblock. With cam, heads and intake it makes about 330 horsepower at the tires through a built 904. My car still has the bench seat, full interior, iron heads, etc. It is not tubbed and drives very well on the street. It is always driven to the gas pump when I need fuel. I have beaten many racers with more motor than I have.

You want a 904, not a 727. The 727 is a horsepower robbing, heavy trans. The 904 takes less horspower to turn and pull down the track. It will definitely hold 10 second power (and way beyond) You just have to build it right.

Cal-tracs are awesome for those of us who want to run a fast street/strip car.

Also, for a lot less than you'd be looking to spend on a trans and a 408, I know where there's a rust free 11 second car for sale. ;)
