Biggest/best TB for LS6 intake??
Got an LS6 for the car and had my stock tb ported/polished before i put the two on my car, first, what is the intlet size on the front of the ls6 intake? Is it worth getting an aftermarket tb to put on rather than my ported stock tb? Would i see any difference? Can I put an 85mm tb on the intake? Car is full bolt on but will be getting a set of heads and cam this winter if all goes well.

Any advantage using a FAST 78 over a ported stock TB? I have both. I was going to run the stock one but after putting the 78 on I like the bling. My motor swap came with the ported stock TB. My rational is to use it since I have it.
