Ls conversion parts recommendation

[69greyghost]

Guys, I have a new Project. I have acquired a 67 convertible camaro. The car has no motor or trans and needs some work, however I am gonna ls it and was seeking some feedback on possible components I should use that are not going to break the bank. I want to get some long tube headers, a gas tank, a radiator, and a possible oil pan for an ls conversion. I would like them to be under 400 dollars each item. Thanks in advance guys.
