Just sort a wondering if there were gains to be made by changing rocker arm ratios on a stock 3.8.

Of course, I'm just not sure how much supporting work needs to be done. Hopefully one of the 7th gen guys will chime in, but I seem to recall a need for different length pushrods on those motors when modifying the valvetrain. Not sure if that is only with cam swap or not.

i run stock PRs on my cam....
may be necessary depending on which rockers you go with.
yella terras come with the new prs, theyre expensive, but worth it imo


most guys go 1.9s, gain will be similar to a stage 1 cam, but a little less. some stagger the rockers. 1.84s/1.9s

Id change the springs the LSx yellow beehives are pretty popular, but you'll need modded reatiners to run them.
Intense sells the YTs, zzp sells the other crap rockers ;)
