750 for long block is enough to do your basics. id recomend checking out engnbldr.com for 100 times better prices and service than LC. for more noticable power its hard to get from just machine work. i went .02 over bore for a fresh start and that does give a greater volume to the engine but not nearly enough to notice a power increase. going .06 over on a v8 you would barely notice the increased displacment. just make sure you use a hiflow oil pump first and foremost. for higher comp you can run 9.5:1 on 87 octane with no problem. id try 10:1 on 91 octane if you want to get creative. for high comp you need to do a few things: go with a overkill ignition (msd 6a witha blaster coil), open your spark plug gap a bit, get cold air into your intake, get exhaust gases out though a header, move hot air out of the engine bay (dont force cold air in). if you run a forged piston you will be fine on pump gas (93octane) up to 11:1 compression. you can get pistons and combustion chambers thermal coated too but that gets pricy.
anyway id just do 9.5 - 9.7:1 compression, bigger valves(engnbldr), a cam(263 or 268 from engnbldr), header(pacesetter) and exhaust(2.0 to 2.25 inch), and play withthe intake and that should keep you within budget and give yourself a noticable gain.
hope it helps, feel free to email me for any help i might be able to give. good luck
