...i got the motor in the car idleing great sounds amazing but when i go to drive it down the street to adjust the clutch out and such i have a problem wiht higher rpm's and by higher i mean probably 2-3 thousand it vibrates like it almost has a dead cylinder, but all the cylenders to my knowledge are firghring. so my question is could it be the timming wich i currently have at 13 degrees or my neighbor seems to think its the carb, it is a edlebrock but is a little tired and worn, i have no idea waht cfm or anythign and he seems to think it has the wrong meetering rods in it and is running too lean, he adjusted around with it and it seemed to help a little so waht is your guys advice, it just gets really choppy, could i have the timming up to high or too low or could it be the carb, the engine is a 289 with a manual 4 speed medium cam stock, bored .040 over nothing else really special, long tubes so yea guys any info would be great just trying to get it so i can drive it to the exhaust place haha
