Hypothetical - Cheap 360 Magnum Rebuild

Gentlemen,

I recently purchased a 1971 duster from another Fabo member. With the duster came a disassembled 360 magnum engine. I would like to build the engine for at least 300 hp and for under $1750 if possible. I am going to run it with a 3.55 limited slip rear end and it will be street only. I was told the cylinders only need honed. The block has been hot tanked and cam bearings have been installed. The heads are complete. They were magnafluxed and no cracks were found. The following parts also came with the engine: Pistons, Windage tray, Piston rods, New double roller timing chain, holley 4 barrel 750 cfm carb, long tube headers, camshaft, lifters, rockers, push rods, timing chain cover, freeze plugs, harmonic balancer, and flex plate.

I figure, figuring all the parts are good, that I will buy at least the following:
New high volume oil pump
Hughes whiplash cam
Main Bearings
Gasket set
Crankshaft(junkyard find?)
Crosswind intake
Machining work?
Valve covers
New Valve springs and retainers for the magnum heads
Ignition
Water pump
Belts, pulleys, etc...

This is my first build ever so I am reaching out for some direction that way I do it right.

Thanks

- Logan
