im building up my bottom end, and when i build my head which crower cams should i get... the 404's (stage 3- mostly strip, rough idle) or the 403's (stage 2). what would it hurt if i got the 404's and used it as a daily driver??

 

404's would be a bit too much for a daily driven car because of the lopey idle. i'd say 403's for daily driving.

 

i have the 404s in my car and i drive the car every day. the idle is a little rough but nothing major. so i'd recommend that you buy the 404s
