Default Porting a stock TB

Can you port a stock LT1 TB to 52-58mm?

Or would you have to upgrade the blade's?

I bet you can't but it never hurts to ask

You can't port the stock tb past 52mm, there isn't enough metal there. I had my stock tb ported to 52mm and I had to get some new throttle blades from Arizona Speed & Marine.
