Ok so go with a 70mm

What are yiour plans. You'll get no real noticable difference from it. I would spend the money elsewhere first. What has been done so far?

If this is all you have I would get the 4.10's that you were thinking about. Just spend your money on the gears. Trust me you'll love them

and reply to your other post

Bolt ons are a learning experience for most, you have to get them all before you realize that you should've spent all of that money on a S/C or a H/C/I swap. But in the long run you'll need all the stuff anyways. I ran a 70mm TB when I had a stock manifold and I just smoothed the lip on the upper plenum because the opening isn't 70mm it's smaller. But I'd save your money and do a whole bunch of bolt ons all at one. Like get a 70mm TB, larger MAF, CAI, and U/D pullies all at once and you'll notice a pretty big difference.
