69 camaro crate engine help!!!!!

[sweet motion]

I'd like to get about 6-700 hp without a blower thru the hood.Any ideas on the best bang for the buck?I want to run an auto trans,possibly a 4l80e. I looked at Paxton superchargers and big blocks, would like efi, any help is greatly appreciated,my budget for engine and trans is about 13grand.
