~450hp from stock stroke 340?

I want to stick with a hydraulic roller to make it more streetable. From what I’ve read up on, people have made 440-470 hp with a hyd roller cam of similar specs.
I don't know what the hangup is with some of you fellers about mechanical camshafts. There's nothing "less streetable" about them. You're reading the dead wrong things and listening to the wrong people. It's your build though. Just remember, you asked for advice. I'm not as confident as some of these guys your combo will make the power you're looking for. I guess maybe bench racin it might. I just don't see it.
