you will be fine with a 150 if you have the fuel to support it.
my c5 is similarly modded and makes the same na numbers your making. i am spraying nitro daves wet kit with a cell (110).
heres my dyno sheet.

just like dawiz said, 150 will be fine as long as your fuel system can keep up and you have a good tune. My stock bottom end car puts down 496 rwhp and gets hit with a 200 shot. we have another customer with a similar setup like you, 445 rwhp and hes been spraying 275 for two years. Its all in the tune

Upgrade to a 255 pump and run a fuel pressure gauge. Like said above you should be able to hit it with a decent shot, but pump failure will def. kill the motor. Also you'll have to get some colder plugs

You might be surprised how many people are doing that and more

But they are willing to walk the tight rope.

When I order my new motor I'm going to see how long it survives on the 200
