I was just reading about a fellow that had built many 87-02 Vortec-based 350s. He likes the RJ350 cam , GM #14097395. Here is where that cam is used. I have collected the parts to build my own Ram Jet, and I spent under $3000. I think the top end, wire harness, and ECU are still for sale from GM. Or you can buy the whole motor in a crate from GM for about $5900. Enjoy.
