Any recommendations for fuel pressure regulator?

I'm finishing up with the 305 to 350 swap ...my sig shows the specs on what I've got. I have a stock 350 TBI. Any opinions on whether I need a fuel pressure regulator? And if so...any opinions on which one to use? Thanks for sharing!

Yeah, go with that GM "marine" vAFPR. You might even be able to use the stock pressure settings. I think it's in the high teens at low vacuum, which is what you're going to need, unless you're running big block injectors.
