I am definitely upgrading the stock TBI with a bored throttle body and better fuel pumps computer upgrade etc. Main reason for the question, i just dont know if its worth the extra $1500 for the 383. At the end of the day, both are basically brand new motors and arent too terribly far apart on performance. Especially considering that both are basically doubling the power output of the stock motor. Both engines will have plenty of power for me.
