John Hennessey said:DC puts a weak cam and weak lifters in the Gen 3 motor to help keep their smog numbers in line. Changing the cam and upgrading the lifters has been worth 30+ rw hp and 30+ rw tq on the Viper SRT10. The down side is that you have to pull the heads (for the lifters). You can actually get the cam out while leaving the heads on if you just wanted to do a cam swap.
make something like that for the Lightning!!!!
