I currently have an SLP 85mm MAFF on my combo but i've seen a lot of cubed cars go with the lingenfelter 100MM MAFF and have good results.

The 85mm delphi unit would work nicely. Could open up the mouth on the ls6 a little and run the larger 3 bolt throttle bodys also. Should work for a nice budget intake setup.

X2 on speed density - no problem on a street car if done correctly... Drove my 408 on the street all the time. I would get a FAST or Vic Jr though... What nitrous setup do you have?
