I'm piecing together my 5.3L, and I didn't get any crossover tubes for the heads.

What does a stock 5.3L engine use for this. I need parts numbers. I know the LS1 intake uses some tubes that connect to bothe the front and back, and the LS6 uses only the front tube and blocks off the back ones, but what does the truck intake require.

Thanks

truck intake uses the front tube and the back is blocked off.

I believe 2002+ have just the front, but earlier models used all four ports.

well I ordered the front crossover tube and rear block offs.....I'm using an 05 block, 04 intake.....so that should work.

I have an '01. Back ones are blocked off. Looks like they started this in 2001 from the previous posts.
