I'm not sure about a First Gen Camaro, but as an example a Thirdgen F-Body can become an expensive prospect due to the cost of the oil pan, headers and accessories/brackets for an LSX based engines.
The LT1 can be a cheaper alternative but I would never do it because of the limited market for parts. Also, in the same situation, both alternatives would require notching the frame to provide room for the AC compressor. I would simply go with a SBC instead of an LT1.
