I have a '66 327 That came out of a truck that im wanting to rebuild. I also have a set of double hump heads thet were originally 1.94/1.5 and the guy i got them from, had the intake valve machined to 2.02.

Im wanting to bore it .30 over maybe, What type of cam,carb,intake could get me to 300hp with good torque. I paln on using my stock 2 speed powerglide, I think my gears are 3:08 or 3:15. Thanks

300 HP is easy. 30 over is .030, 30 thousandths, Go with Flat top pistons

Carburetor : 570 street avenger. or stock Quadrajet or 600 CFM
Intake Manifold : Edelbrock Performer
Camshaft : Voodoo 60101 Duration 256/262, Lift .454/.468
Headers : Summit brand

Getting 300 horses out of your 327 shouldn't be any problem. Making it feel like it has power and "good torque" with a powerglide and 3.08's is another story. Swapping out the glide for a T350 would be fairly easy and it would feel like it gained a whole lot of power.

By rebuild you mean?
Do you want to machine the block and everything?
Deck it for a good quench depending on what gasket you want, throw in some decent pistons, shoot for around 10:1, double humps can make a lot of power depending on how far you go with them.
I know of a lot of strong running 327's with 9.6:1-10:1, headers, good dual plane intake, smaller holley carb, a good old 268 comp cam, they will run stripes around bigger motors.
My setup is a .040" 327, around 10.8:2, comp cams 286H-10, 190cc 58cc chamber 2.02/1.60 valves, runs strong, it's a dog with 3.08's and a manual trans, but runs very well. Throw in some lower gears with a good stall with the glide, or as said before get a th-350 or a 700r-4 or 200r-4 if you can find them and it will run even better.

The high gears and 3.08's are going to hold you back, they really limit how much cam and so on you can run with that motor.
