If you shop really really well, you can get a full h/c/i setup for that much.
The depending factor will be how much you pay for the heads.
Keep an eye out for used Twisted wedges, edelbrock rpms, gt40x and afr 165's (although the afrs are a long shot). $800 (used)
A pro m(old pro m) or pmas meter calibrated for 24's.
65 or 70mm TB and spacer.
Other things you'll need:
Arp head bolts
Ford racing timing chain
Ford racing water pump
A cam
Roller rockers
A full set of gaskets
Pushrods
155 or bigger pump
For an intake i'd consider a gt40 or cobra, gt40 being my preference, but the cobra is as good but noticeably cheaper.
