4.8 build HELP NEEDED I have a 4.8 Silverado that has long tube headers and 3.73 gears with a locking diff and that's it right now.
I want to build the top end of the engine but I need help. I have a ls6 cam, TBSS intake, throttle body(need xlink), and fuel rail in my garage.
I want to install all that, Port and polish the heads and valve job (2.5 upgrade from Texas-Speed when I can afford it), roller lifters (if it is worth it, possibly change ratio), then get a tune.
Will all this work and what is my expected RWHP?
Im not interested in changing engines so don't waste your time telling me that.
