What would you guy`s do. I need to make up some killer ET on the top half of the track.



If it will be a new combo all together, I'd opt for more CR since you're in the short block, but have someone pick a cam that uses all the available variables (gear ratio/shift recovery/etc.) to optimize/reduce your 330'-1320' times.

More squeeze without other changes in cam duration, fuel spec and timing may also result in more torque that can't be coupled to the track in the first 330', thereby slowing 1320' ETs even with more power. That balance is tough to achieve when you're traction limited. Been there, done that.



Another way is to run a lesser converter, soft out
of the hole and big charge on the top end, but its
a balance on the converter where its not a mutt
out of the hole
