hey guys,
Just a quick one currently assembling my 383 for a 78 camaro. It has a scat crank, Im pretty sure these use a 400 harmonic, can anyone clarify whether the 350 and 400 bosses are the same diameter or are they phsically different. Secondlt its running a turbo 350 will the flex plate be the same or do I need a new flex plate as well.
thanks Steve
