Is it possible, without any mods to the heads, lower end?

 

how many times do you want low 11's?

You can always add spray.

 

That is the magic question
Can it be done, hell ya and many have (even 10's on a stock Block w/Turbo)
But how long will it last, ARE YOU A GAMBLING MAN .....

As IM just said N20 would be the easiest and cheapest way there, but LOW 11's on a SB will not last long for MOST motors. Some may get away with it a while, others could let lose instantly. Now 6's - 8's is another story, and very do-able....

 

5's

4's

 

with a head start I can do in 3
