LS1 head & Intake swap
#1
undefined
Anybody out there performed a head/intake swap on an 03/04 silverado 4.8/5.3/6.0? If so I have a couple of questions.
how did the drive by wire throttle body mount up to the intake?
any problems with the injectors or fuel rail?
What about waterpump interference?
what kind of dyno numbers did you post, or e.t.'s?
did you have to change VE tables on edit?
How far did you deck the heads?
I have all the parts just considering biting the bullet now while I have down with the 212/218 cam changeover. I am wondering what problems I should anticipate. OH Yeah richard is going down!!

As far as the LS1 intake swap goes, I'll look one of my old threads and give you the names of some people who have done it. I know it can be done, I think the only thing that has to be modified is the injectors/rails some how...
