LS6 Stuff for my truck
OK so here it is, I am get a deal on and LS6 Heads/Cam/Intake with about 1500 miles from a friend of mine. Right now my truck is stock, in the mail is a built trans and a 3k Stall. Now, in the coming year I plan to do CAI, LTs, E-Fans, and ASP Pulley. Now here is my question, should I have the LS6 heads ported? I know this sounds like a stupid question, but my fear is that with the 5.3, the Z06 Cam, and the LS6 intake, if I port the heads I will lose to much bottom end for the 3k stall due to the small displacement of the engine. Anyone cares to offer up their opinions I am listening.

Well With A 3k Stall Depending On How Lose The Verter Is You Don't Have To Worry About Bottom End Just Make It Match.depending On The Year Of The Cam On What You Want If It Is 02 And Newer 3k Lose Would Work Realy Good.

The cost to port heads as you mentioned would be close to the cost of pulling the engine boring it and installing 5.7 slugs & balance the bottom end.That is if you can do the labor yourself.

You don't stop do you? A man asks a quesiton, and you offer something COMPLETELY different then what he is asking. Do you take the time to read a post BEFORE you comment? Or do you just offer useless info because you have nothing better to do??? The man wants to add heads, cam, and an intake to his motor.....and you offer back and tell him to rebuild his motor and bore it for 5.7 pistons......WTF!!!!!
Back on topic....
I would not port the heads, unless you plan on stepping up to make more power later, but inthe meantime, the ported heads with that combo will do you no good, same with the intake, truck is fine for what you are wanting. The LS6 cam for your truck will move the powerband up some, and you will lose some torque down low as well, and adding the intake and heads would only make it worse. I would stick inthe cam with the converter and trans...and see what you think about that, and go from there.
