Whats realistic to expect out of my 305

Sorry to ask another 305 question where performance is involved but its cheaper to light mod my 305 then get a 350.

I know my 87 lg4 made about 160 hp stock. So with exaust done (headers back), rpm performer intake, and rv cam about how much hp should i be making? Around 230?

If you are good with tuning and didn't goof any of the part installs by leaving restrictions in place, then yes that sounds about right.
