383 problems
383 problems I just installed my new motor and my pullies are off a couple of hairs. just wanting to know if any one else has had this problem before? Also would the stock injectors on a 383 make the car run bad and or vibrate alot?.... thanks for the help

Maybe some more information on how it is running bad would help is this at idle or accelerating or WOT. No issues with the pulleys on mine.
Sounds like your balance hub isnt all the way sat in, you need to take the bolt out and get a threaded rod the same thread size (fine), and get some nuts and large washers to get it the rest of the way on, thats the on thing where if you off a few hairs, it would be there, and no where else. Nothing else has that sort of adjustment for the being too forward.
what size injectors would be good... i don't need to go all out just something to give me a better alround performance..... and yes my motor was internally balanced also. So i will check with the weight on the balancer

you should be good with some 36LBS or some 42 LBS... Yeah check that weight on your flywheel... Oh and don't forget you will need a tune with the injector upgrade
i should also note that the car did not start a vibration until i put the exhaust on it. While it had open headers the car did not vibrate. Or maybe it did i just could not tell because of the open headers.
