yaw I think if you launched at half throttle you would pick up at least .2 what cam do you have?

 

stock cam.

also forgot, stock airbox and tube too

 

Wow that's good! I'd say the heads probinly droped a second off your time

 

Nah, honestly I didn't feel much gains from the heads. The 4.10s gave much more "seat of the pants" than the heads did. But then again, with the tiny lift on the stock cam, it doesn't really take advantage of the heads at all.

 

yaw I hear yaw, any way u look at it that's a verybrespectable time for your mods! IMO
