Why can't i go faster?
#1
Best time 16.24 @ 87.3 mph . mods are in sig. I am a second faster than my old stock 4.8 rcsb but I think that i should be faster. It might be that it has 3.42's or it could be the strip. any suggestions would help.

Thats about right.. the efans and intake are your only performance mods really.. and they dont make dramatic increases... look into a posi rear and 3.73's or 4.10 gears. And if you want to open up the motor, get a cutom tune and do a cam/spring swap.
