Im sorry, the motor is 408". The car is 2940 with me in it and its been a 5.60 @ 127 on the sauce so far but havn't had it on the dyno to tune it yet. A good friend of mine is looking for some 360-1's so I thought about selling him mine and stepping up to the 245cc cnc heads. Mine have already been ported and just curious if I will see an improvement with the cnc heads over fully hand ported heads.
