HP and times
 

Sup all,

I have been restoring some minor stuff on my car and have found out that i have a BIG holley and a shift kit and im putting in a K&N filter and im putting in a edlbrock housing for the air filter, and i was wondering how much HP i might have gained from the carb and filter, and how much HP might i gain if i take off the second muffler on my car and just run the 14" glasspacks? I know these are minor mods but i was wondering if i might gain like a tenth or 2 and maybe like 15 HP. What kinda ET and MPH am i looking at stock, i know i have a C-6 with a 9" and i think 4:11's
Any info helpfull
