quick (and probably dumb) question
 

Why doesnt anybody have a LT4 kit for a 1993 LT1? Its always 94 and up. Does the 94 LT1 have something that the 93 doesnt?

If I am not mistaken the 94 has the aluminum heads and the 93 has the cast iron heads. but I am not 100% sure that is the reason. I think that the runners on the fuel rail were set up a little diffrent on the 93s.

and the 93 camaros did not have a mass airflow sensor.
