Looking for opinions on low budget 360 build

It will be hard for what you need to stay at 300.... If you had a good running 360 then 300 could really perk it up
Thanks guys,
I'm not looking to stay at $300, just starting with the $365 kit plus machining costs (good point about bringing the crank too, rumblefish). I just can't spend thousands, maybe $1500 all in. I dream of new heads, roller lifters, etc...but those I think are a dream for me and my wallet.
