Diesel/Gas Conversion for 84\' K5 Right now I have a daily driver diesel blazer. I have no problems with it but I also have another engine that has been sitting in a boat for a year. The engine is a pretty good 350 with all marine parts and puts out around 350 hp and I hate to see it just sit and get old. Unfortunately I live in California and I know all about the strict smog rules for street legal cars. I was wondering if the diesel cars in California had to be checked to make sure if they were diesel, because if they did not, what would prevent someone like me from putting in a gas engine? I mean, if I got pulled over i dont think a cop would look under the hood to make sure its diesel. I was wondering what people thought about this cause I am really tempted to do this.
