first off, I have an 04 that is bored.020 w/ a hot rods crank, vforce 3's, and on and on(you all know, the usual)... I am buying the 240 kit and was wondering what machining, if any at all has to be done? Im thinking there may be some clearance issues with the bottom end and the+3 crank and may need some fine tuning... I am not a mechanic, but I do know my way around motors. Can it really be bolted right on, and if anyone knows what it brings the final compression ratio to that would be awesome! please no BS cause this thing is a sleeper 400ex eater!
