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!
