Maybe check vacuum. Should be 18" or higher I think. Stock is much higher than that. Do a search for tbi vacuum and you may find out the actual readings.

Best way to know... pull the timing cover off and look at the front of the cam. Not the easiest but it will eliminate any "what if"s... there may or may not be a number on it, just forewarning.
