I have a '93 with a 393 short AFR heads and a mild custom cam. C3P1 computer and a older EEC tuner thats about to be installed. Stock injectors. Superchargers still on a shelf fo rnow. Can anyone help me out with a ball park tune so I have somewhere to start? Thanks

A ballpark tune is not going to work on a 393 with stock injectors. The injectors are way too small. When I put heads/cam/exhaust on my 351, the 19's could not give me enough fuel. That was after having the Tweecer dumping as much fuel as it could with the 19's.

This was without the Vortech on it.
