Nice ride!
I did the 24x / 411 PCM conversion in my El Camino with a 396 LT1 stroker (it was a 96 OBD2 Lt1). That costs a lot of $$ but the tuning is great with HP Tuners
Yuo could go OBD1 with a 94-95 PCM and use Tunercats or EEhack for much less
If your PCM is a 93 maybe someone else can suggest a solution.

 

If 1994-1995 PCM, I would use TunerPro RT and EEHack. Both Free and very capable.
