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

With the nitrous you should be able to get in the 7's in the 1/8.
I would recommend a Fogger system. It is easier to get the cyl to cyl distribution right, but is more expensive. I have both a plate system, and a fogger system, and jetted at the same "advertised" HP rating, the fogger is quicker.

PS: My 66 Cuda is a full street legal type car minus exhaust. 170 cubes and weighs 3250 on the starting line. It will run low 8's in the 1/8 on 150 shot.

Thanks Charlie! This is exactly what I was looking for! A couple a years ago, there was a slant running in a footbrake class I was in. While I was in the staging lanes, about every racer was taking a look at the car and I was as well. It really peaked my interest in the /6. I'm going to go with the fogger set up as you recommended and committing to the /6 build. Will the stock crank/rods hold up with this combo, or should I upgrade these components?
