what about obs?? Is it worthwhile to get some aftermarket ones or will the stock manifolds work?

The stock 5.3 manifolds will work, but headers would definitely be the ideal way to go.

The baddest headers ever: http://www.lmperformance.com/2807/1.html

Those will fit the cars, not the trucks.

That sucks. Couldn't you make them fit somehow?

not without some SERIOUS modifications. Like, you might be able to use the flanges from them and that's about it.

Oh well. Hedman Headers makes some longtubes that fit the 5.3 right? Are they better than Borla shorties?

I wonder if those made for the hummer will work on a pickup? Edelbrock makes some and a guy on Ebay sells them for $280 with free shipping.
