well, what all is coming with ur 6.0? one thing i would check is is the 6.0&#39;s intake manifold has egr. the 4.8 probably doesnt and if the 6.0 does itd be easy to just bolt the 4.8&#39;s manifold onto the 6.0 and have ur tuner delete the egr.

You&#39;ll need the PCM retuned for the 6.0L engine. A couple friends, a hoist, a toolbox full of tools and a case of beer is a good start. Be sure to check the crankshaft length before trying to stab it in. Be sure it&#39;s the same length as the one you&#39;re taking out and if it&#39;s longer, see if it has an extension pressed on it that you can remove. Reuse the 4.8 flywheel unless you know everything is identical.

im sure it comes w/ intake but i will just put my 4.8 one on instead. it will probally be about a month or two before i get it i was just seeing what all i need. im gonna order a 4.10 posi and programmer while im at it. do i need to beef up the trans? i already have a shift kit just havent had the time to put it in.

That should be a nice easy boost of HP&#33; Would that be called stock, or a bolt on?

[alabamachevy15]

Is it time for the transplant? I&#39;ve got a 4.8 CC that needs a 408. If they don&#39;t believe it&#39;s a 4.8 the can check the VIN.

i think im gonna get a 4.8ss sticker&#33;
