I am having a really hard time trying to find what all made up the Boss 302 engine. One website I went to said all boss 302s only came with a 780 CFM carb. another website said they came with 920 CFM carb. I have no clue how the exhaust set up is, what the CR is, what heads were on it, or intake manifolds. Each website I go to is preaching a different story about the boss 302. So do any of you guy know what the carb. the heads, the intake manifolds, and the exhaust size is, or if the car even had headers?
