300 HP out of a 318, is it possible with bolt ons?

Hey everyone, was wondering if a 300 crank HP 318 build was do-able with bolt ons- and what else might I need to reach that??
318 build list:
- eddy 4 barrel intake & 600 cfm carb with 1 inch spacer
- Mild cam (Hughes whiplash)
- Hedman long tube headers, duals running to flowmaster super 10s
- Jegs distributer and NGK plugs
*Motor is fairly fresh and pulls to 5000+ no problem*

I understand majority of SBM's suffer from flow restriction and deathly low compression, but I do not wish to tear my motor apart soon, and just want a streetable small block for now! If anyone has any idea where I'm at horsepower wise currently or suggestions to hit 300 HP at the crank, please let me know!
Yep, go for it. Sadly, teens don't get put on the dyno very often so there's not a ton of numbers out there. Hot Rod magazine built a 400 horse teen (supposedly) with zero deck pistons, a 230°/.512 Comp Cam The lift was using Magnum heads and their 1.6 ratio rockers. Intake was a MP open plenum with a 750 Demon etc, etc. Here's a link. I think a zero deck Teen with some mildly massaged Speedmaster heads and the right cam could get to 400 horse easily.
