Looking to do 4.8 single turbo build any help
i was going to use stock bottom end and the 243 heads change out to a 1.6 year rocker but looking for a good set up on cam and valve springs set up for a 76 mm precision looking to be around 600 on about 12 lbs of boost thanks for any help guys
And I don't even know anyone that makes 1.6 ratio rockers for the LS engines.
Since you have a 2008, no need to upgrade the bottom end.
