My friend bought an 81 tubbed camaro with a 454ci, 750cfm dbl pumper, 3spd auto with ratchet shifter, 4.55 differential. That is all he knows about the car and he is trying to tune it (1/4 mile time was 14.24 sec shifting @6000 rpm at elevation of 4000 feet). My stock C5 vette with 350ci and 2.73 gears runs the same! Can someone please help with a little tune up info...we are mechanically challanged...lol (i.e. timing, jet size and anything else that would help make this thing go faster)
