What performance upgrades would get me to 300hp without machine work?

Headers would be the only upgrade that will give any performance upgrade.Roller rockers are a waste of money.
New O2 sensors are fine, as they are a maintenance item.
Fuel pump is the same as it is intank. Leave it be for now, Dont mess with the fuel pressure ....yet.
Throttle body spacer.....meh.$$$$$

5.7

I think I responded to your other thread regarding this. Headers are about the only bolt on upgrade you can do. and that will not get you close to 300 hp. If you want to get in that vicinity I'd recommend going to an LS1 or LT1 engine. That would net you near 300 hp. Otherwise...you'll have to tear down that 350 and do some internal alterations to get anywhere near 300 hp
