Ok, so I am trying to decide what to do about my cams. I currently have a set of Crower 272s. I want to keep the stock valve springs. My car is a DD but I am also trying to better my 1/4 mile times and am about to get my car tuned by Buschur. So my question is, to better my times, should I swap out my 272s for a set of 280s? My mods are below.

for 1/4 mile racing 280s will def giving you the edge over 272s on the top end.

 

i had 272's and wanted to go bigger so i got comp 280's and they are way better def. a difference.
