Default 5.3 LM7 liter vortec intake swap, which one?

Ok i know theres my 76 mm or 72 mm i cant remember but stock intake.. its full of oil.. im gonna clean this or swap it? the MAP Sensor was coated with oil.. its bothering me cause i got it from local junk yard. Should i get the LS1 intake, or another truck intake? Im gonna turbocharge it later. plan on high energy cam from comp cams. the small one from 1200 to 6000.... so i dont mind replacing it with another truck intake
For your question! the oil came from it being flipped over in a 01 silverado

Oil won't hurt the intake, just wash it out and run it. It's really not worth upgrading to the LS1 intake unless you need to for clearance reasons or want to for aesthetics. Then it's best to just skip to the ls6 intake or FAST because the LS1 intake sucks.

I have no experience with the LS1 intake, but everything I've read says that the original truck intake (74mm) will out perform the LS1 intake.
