recently ive pondered the thought of building up a 396 block from a chevelle that i have for auto class. as i thought about that i considered dropping it in my camaro, as of now i have a carb'd 305. so my question is, how much can i bore out a 396, will the 700r4 line up to it, do i have to swap motor mounts, and will all the wires and connector be direct plug ins such as temp sensor and throttle control and what not. also do they make headers for a 396 to be used in a thirdgen
