Actually the fan is what got me my first 13sec pass, i got some good power gains, i also removed front swaybar, i used to be a firm believer in 4.10s, but 373's are probaly better so you dont have to go to 5th gear on the strip, some people dont have to if their motor can pull high rpms in 4th (heavily modded), but for near stock id get 373.
