Maybe I'll just beg then, man I have HAD IT it trying to get this code figured out. I just wish someone could look and say "oh yeah, thats a 283 from back in 68." or whatever it is. I have to find out what it is, so i can get rid of it. I am a modern suped up 350 or 327 fan myself. Even a 396 would turn my crank- but not a 283- if thats even what I have.
