Question re intake manifold
It appears I will be pulling my intake manifold off to get at a bad knock sensor. My question is, while its off, can I get it ported? How detailed and exacting does a porting need to be? Is it just grind away, or is it take .005mm off of this and .010mm off of that? Also, who would do this type of work, a machine shop? As it costs $500 to get an LS6 intake manifold, could it be done cheaper and better porting my existing one?

Re: Question re intake manifold (jlamay)
Nobody has had good experiences with ported manifolds really. A few may have gotten more peak hp but really bad lowend power, which is why nobody really sells ported manifolds right now. Its plastic. Doubt you'll find a machine shop that'd touch it, and if you did, you'd be best staying away.
Get the ls6 manifold or keep the stock one as is.

J, you can get the new intake... but dont expect any SOTP improvement. :nono: Most swaps on a car like that will only get you 5 rwhp at best.
