Look in Summit, Jegs, GM Performance, --- any where but eBay.
GM makes a few that fall into that power range and I don't think you can beat them for reliability. Edelbrock makes some too, but I think they are way over priced.

Check out Gilbert chevrolet (the old Sallee dealership) they have a line of GM performance engines that they "modify/build up". If your after a hot small block, check out there "Super AFR ZZ4." It puts out 465hp and 440ftlb torque. Not bad for a 350. They have many others as well. Worth a look.

for 450 hp range I'd go with a stroker motor because it will have better street/driveability maners Otherwise a standard bore and stroke 350 w/ 450hp probably wont "come to life" until you get it above 4000 rpms.

I used to have a iron headed 383/465 HP from AR Racing in Virginia and had very good experience with it. I paid $2995 for that engine and ran mid 11's in the 1/4 mile... However, other forum members had bad experience with their engines. I actually bought another engine from them (which was a lot more $) which made the car run in the very low 11's. The only complaint that I'd have about them was that they used a different cam for the build as I requested even though the cam used was very similar in specs...
For me, I really got a lot of engine for the money but their quality seems to vary..
